Bluetooth peripheral sample auto disconnects "ST B_L4S5I_IOT01A Discovery kit" #28343

Closed parthitce closed 4 years ago

parthitce commented 4 years ago

Describe the bug Bluetooth Peripheral sample failed to work in ST B_L4S5I_IOT01A Discovery kit board.

Disconnection with the host after, [00:00:29.020,000] <err> bt_hci_core: packets count mismatch

To Reproduce Steps to reproduce the behavior:

Zephyr steps:

  1. west build -b disco_l475_iot1 -s samples/bluetooth/peripheral
  2. west flash

Linux bluetoothctl:

[bluetooth]# scan on
Discovery started
[CHG] Controller AC:67:5D:3C:4F:AF Discovering: yes
[NEW] Device 50:5F:38:1B:FB:C5 Zephyr Peripheral Sample Long
[bluetooth]# scan off
Discovery stopped
[bluetooth]# trust 50:5F:38:1B:FB:C5 
[CHG] Device 50:5F:38:1B:FB:C5 Trusted: yes
Changing 50:5F:38:1B:FB:C5 trust succeeded
[bluetooth]# connect 50:5F:38:1B:FB:C5 
Attempting to connect to 50:5F:38:1B:FB:C5
[CHG] Device 50:5F:38:1B:FB:C5 Connected: yes
Connection successful
[CHG] Device 50:5F:38:1B:FB:C5 Connected: no
[DEL] Device 50:5F:38:1B:FB:C5 Zephyr Peripheral Sample Long

Expected behavior Connection established and should be able to view the profiles and examine GATT attributes from bluetoothctl.

@parthitce can you clarify board you're using ?

Bluetooth Peripheral sample failed to work in ST B_L4S5I_IOT01A Discovery kit board. west build -b disco_l475_iot1 -s samples/bluetooth/peripheral

These aren't the same board. ST B_L4S5I_IOT01A is b_l4s5i_iot01a.

Btw, I've tested samples/bluetooth/peripheral successfully on both boards, with 2 mobile app (ST BLE profile and nRF Connect). Will try to do some more testing using bluetoothctl.

I wasn't aware there are different revisions available. Mine is B-L475E-IOT01A1 (printed on the PCB)

Ok, so this is indeed disco_l475_iot1. ST B_L4S5I_IOT01A is based on STM32L4S5I. I agree this could be confising.

@parthitce I've been able to test successfull using bluetoothhcl also:

@parthitce I've been able to test succesfuly:

@erwango Thank you very much for the tests. I will re-do the tests today and update my results. I was sure that the problem was persistent with constant disconnection and device deletion in bluetoothctl end.

Also there was another test which was failing, nrf52840dk acting as central and disco acting as peripheral. Will confirm my tests again. Thanks again.

parthitce commented 4 years ago

@erwango It's working fine now. I couldn't reproduce the problem anymore. Sorry for the noise, closing it.
