Failing on ubuntu 22.04 (linux mint 21) - LE Set Scan Parameters  Command Disallowed

Hello,
I am facing trouble trying to make goveebttemplogger work, may be because of latest change in bluetooth stack.
The issue happens on first call of hci_le_set_scan_parameters(device_handle, 0x01, htobs(0x0012), htobs(0x0012), 0x01, 0x00, 1000)
and it is failing with error : Error: Failed to set scan parameters: Input/output error due to the action being disallowed (see btmon trace below).
On the other side I am able to complete a manual le scan with bluetoothctl on the very same host and see my Govee devices.
So to me it looks very much like this issue where bluetoothctl works but not hcitools.
It seems people recommend to do a hci_reset before see 1 & 2.
Yet I don't understand how the code should be change to have a succesfull bluetooth initialisation - I tried my own code, but it fail the same.  I am completely new to bluetooth stack, so can help much more.
Regards,
Yves

I'll have to look into this more. I've not been using btmon, but instead use Wireshark for most of my Bluetooth debugging. It looks like we are using the same version of Bluetooth. Comparing what's happening on your machine to mine might be easier if the sequence numbers matched up. You can see that I start receiving advertisements by sequence 11.
Were there a set of hci commands 1-14 in your log?
Is GoveeBTTempLogger exiting on its own after sequence 20 on your output?
I can't remember why I first set the scanning parameters to 11.25msec and then issue a second scan parameters command to 500msec. It was probably something I saw happening in my pcap log from the android device.
I'm running the program in a different window with the command: sudo ../visualstudio/projects/GoveeBTTempLogger/bin/ARM/Debug/GoveeBTTempLogger.out

Sorry, I didn't think of restarting btmon between my attemps.
I updated my first message with a new trace starting at #1:
GoveeBTTempLogger exit on its own, when it encounter the first error at #5, during initialization (at goveebttemplogger.cpp#L2072 in the code. I get that from the debugger.
Nothing was retrieved from the bluetooth network at this point, since it is way before the while (bRun) {...} loop.

Ok. And you are definitely running GoveeBTTempLogger with full root privileges? Just checking more possibilities.

I've been digging through the library headers and there's not a simple reset command I can call for the HCI, so it's going to take longer to figure out how to add that command in the code.
hci_send_cmd is promising, but I don't really have experience sending direct hardware control interface commands.
HCIDEVRESET is defined here, but I'm not sure how to use it.

@yduf If you run bluetoothctl does it go into scanning mode properly?

Yes I am running GoveeBTTempLogger with full root privileges.
But the funny things is that it is not necessary to use sudo for bluetoothctl.
Not sure What you wanted to compare with the above trace.
The way I have used bluetoothctl to scan my govee devices:
bluetoothctl (no sudo needed)
$ bluetoothctl
Agent registered
[bluetooth]# menu scan
Menu scan:
Available commands:
... # remove menu displayed
[bluetooth]# transport le
[bluetooth]# duplicate-data on
[bluetooth]# back

@yduf I don't really know what I was trying to see, mainly if a known program that could scan on your machine operated differently on my machine.
As part of my visual studio build process, I run this command: sudo setcap 'cap_net_raw,cap_net_admin+eip' $(RemoteTargetPath) which allows the bluetooth stuff without requiring root access each time.
I've now pushed a new update to my code that sends an HCI Reset, and it doesn't seem to have any detrimental issues on my development machine. Let me know how it changes the btmon output on your machine.

(delete previous post to clarify issue)
Got latest version from master, and tested it. It goes a bit farther but fail in hci_le_set_scan_enable
But when doing so, it's breaking bluetooth on my system, to the point that restarting bluetooth service is not sufficient,
and the only solution I have for now is to restart the computer.
When this happens launching bluetoothctl after goveebttemplogger gives me
Failed to start discovery: org.bluez.Error.InProgress

bluetoothctl working fine

$ ./GoveeBTTempLogger/usr/local/bin/goveebttemplogger => failure is expected here

bluetooth is broken now

$ bluetoothctl
Agent registered
[CHG] Controller CC:D9:AC:C3:14:A4 Pairable: yes
[bluetooth]# scan on
Failed to start discovery: org.bluez.Error.InProgress
[bluetooth]#

and dmesg keep telling:
[  742.315277] Bluetooth: hci0: Opcode 0x2039 failed: -16
restarting bluetooth service won't fix that.

@yduf Can you look at /usr/include/bluetooth/hci.h and see if these entries are the same as in my version:
#define OCF_LE_SET_SCAN_PARAMETERS		0x000B
typedef struct {
	uint8_t		type;
	uint16_t	interval;
	uint16_t	window;
	uint8_t		own_bdaddr_type;
	uint8_t		filter;
} __attribute__ ((packed)) le_set_scan_parameters_cp;
#define LE_SET_SCAN_PARAMETERS_CP_SIZE 7

#define OCF_LE_SET_SCAN_ENABLE			0x000C
typedef struct {
	uint8_t		enable;
	uint8_t		filter_dup;
} __attribute__ ((packed)) le_set_scan_enable_cp;
#define LE_SET_SCAN_ENABLE_CP_SIZE 2

the fact that I'm calling higher level functions in hci_lib.h should make any changes there transparent, but I'm grasping at differences now.
int hci_le_set_scan_enable(int dev_id, uint8_t enable, uint8_t filter_dup, int to);
int hci_le_set_scan_parameters(int dev_id, uint8_t type, uint16_t interval,
					uint16_t window, uint8_t own_type,
					uint8_t filter, int to);

The master branch has the HCI_RESET removed from compiling now.

I have check and they are exactly the same, this is are mine:
#define OCF_LE_SET_SCAN_PARAMETERS		0x000B
typedef struct {
	uint8_t		type;
	uint16_t	interval;
	uint16_t	window;
	uint8_t		own_bdaddr_type;
	uint8_t		filter;
} __attribute__ ((packed)) le_set_scan_parameters_cp;
#define LE_SET_SCAN_PARAMETERS_CP_SIZE 7

#define OCF_LE_SET_SCAN_ENABLE			0x000C
typedef struct {
	uint8_t		enable;
	uint8_t		filter_dup;
} __attribute__ ((packed)) le_set_scan_enable_cp;
#define LE_SET_SCAN_ENABLE_CP_SIZE 2

int hci_le_set_scan_enable(int dev_id, uint8_t enable, uint8_t filter_dup, int to);
int hci_le_set_scan_parameters(int dev_id, uint8_t type, uint16_t interval,
					uint16_t window, uint8_t own_type,
					uint8_t filter, int to);

@wcbonner with your reset implementation and looking at bluez/lib/hci.c I got a better understanding of how to issue hci command directly.
To the point that I successfully implemented my own version that mimic the blutetoothctl sequence captured by btmon.
As I was hoping, doing the same seq, allows to do trigger the le scan without failure.
While there is not much difference in the args used, it seems that using extended operation that are not avaible in bluetooth/hci_lib.h make it works. And no need to call reset at all.
I did not do a full implementation, just the init code, so it ends on its own at step #6, just after having started the scan.

I was looking at the function hci_le_set_scan_enable as a model for issuing the extended scan parameters but didn't see the structure values in an easy format to know how to fill the bt_hci_cmd_le_set_ext_scan_params structure.

Sure:

called like this:

if (set_ext_scan_enable( socket, 0x01, 0x01, 1000) < 0)
      throw Error( "failed");

@yduf I've pushed a new version of the code that first attempts the regular le_scan and if that fails attempts the extended le_scan. I was not able to test the extended scan, and don't know if the advertisements will be recognized by my program when requested in this fashion.
I initially tried replacing the standard calls with the extended calls, and that didn't work for me.

I found the definition for BT_HCI_CMD_LE_SET_EXT_SCAN_PARAMS in the monitor program, but not in the Bluetooth development headers to be able to easily recognize if it's defined at compile time. Similarly, BT_HCI_CMD_LE_SET_EXT_SCAN_ENABLE is in the monitor code.
I don't really like that I'm defining the constants in my code and then basing the calls on whether they are defined. If you can find them defined in the standard headers on your machine, I'd appreciate knowing in which files they are defined.
I'd also like to know if you receive LE Advertising Report (0x02) or if you now receive an extended advertising report?

So far the same on my side, found BT_HCI_CMD_LE_SET_EXT_SCAN_PARAMS only in the monitor program.
Your modification solve my bluetooth issue, as far as scanning is concerned => now scanning is succesfull.
But now, Ctr-C stop the GoveeBTTempLogger (signal is caught), but it doesn't stop scanning.
sudo btmon, show that scan continue while GoveeBTTempLogger is terminated.
And I see following event continuing to come through btmon:
> HCI Event: LE Meta Event (0x3e) plen 57                                                     #117 [hci0] 11.808571
      LE Extended Advertising Report (0x0d)

@yduf New code push that hopefully uses the extended call to stop scanning properly.
The default service file passes the parameter --svg /var/www/html/goveebttemplogger/ so that's the directory that SVG files should be written unless you've overridden it to go elsewhere.

This one solves all bluetooth issue. Many thanks!

Just a quick followup for completeness:
Performing extended scan, produce event of type bt_hci_le_ext_adv_report: (private type again), that are incompatible in layout with le_advertising_info.
So in the end, the current fix allow a smooth bt  scan with no errors on my kernel & system. But events gathered are not recognized because of the different binary layout. That's the reason why I was not seeing any log or svg files.
Yet I am not reopening the issue:  it seems that currently I am the only one facing the original problem.
With the knowledge gained from this issue, I created my own simple monitor.
It's use the extended parameters described above, and cover my use case so far.
Thanks again for your help!
PS:
This are the extended event reported:
struct bt_hci_le_ext_adv_report {

vs the "regular" one

	uint8_t		bdaddr_type;
	bdaddr_t	bdaddr;
	uint8_t		length;
	uint8_t		data[];
} __attribute__ ((packed)) le_advertising_info;

Just a quick followup for completeness: Performing extended scan, produce event of type bt_hci_le_ext_adv_report: (private type again), that are incompatible in layout with le_advertising_info.
So in the end, the current fix allow a smooth bt scan with no errors on my kernel & system. But events gathered are not recognized because of the different binary layout. That's the reason why I was not seeing any log or svg files.
Yet I am not reopening the issue: it seems that currently I am the only one facing the original problem.
With the knowledge gained from this issue, I created my own simple monitor. It's use the extended parameters described above, and cover my use case so far.
Thanks again for your help!
PS: This is the type of the extended event reported:
struct bt_hci_le_ext_adv_report {
	uint16_t event_type;
	uint8_t  addr_type;
	uint8_t  addr[6];
	uint8_t  primary_phy;
	uint8_t  secondary_phy;
	uint8_t  sid;
	uint8_t  tx_power;
	int8_t   rssi;
	uint16_t interval;
	uint8_t  direct_addr_type;
	uint8_t  direct_addr[6];
	uint8_t  data_len;
	uint8_t  data[0];
} __attribute__ ((packed));

vs the "regular" one
typedef struct {
	uint8_t		evt_type;
	uint8_t		bdaddr_type;
	bdaddr_t	bdaddr;
	uint8_t		length;
	uint8_t		data[];
} __attribute__ ((packed)) le_advertising_info;

@yduf This is interesting to me, and I've mostly completed my obsession with downloading historical data.
I'd originally wondered if enabling extended scanning might return extended results, but without firsthand knowledge I've been hesitant to try to add the support for an unknown packet.  I was just looking at https://ubuntu.com/download/raspberry-pi and it looks like I should be able to create an Ubuntu Pi on a spare sd card pretty easily.
Your original post described the code you were running on and processor as:
uname -a
 Linux yves-huv 5.19.0-28-generic #29~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Dec 15 12:05:40 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Do you know what release you are running?

Sure it's a close derivative of ubuntu:
OS: Linux Mint 21.1 x86_64 (issue was on 21.0 but I upgraded recently)
Kernel: 5.19.0-35-generic
It should correspond to
linux mint 21 (vanessa) <-> ubuntu Jammy 22.04 LTS

I spent a while getting Ubuntu up and running on my Pi4 and it seems to use the standard commands instead of the extended commands. Looks like I'm not going to have a system that I can test extended events anytime soon.
In one window I ran the command ./GoveeBTTempLogger/usr/local/bin/goveebttemplogger --log /home/wim --svg /home/wim --only FF:FF:FF:FF:FF:FF
While the other window I logged in, ran uname, and then btmon:
