Hi,

My custom device with custom firmware don't respond to LL_FEATURE_REQ so the device disconnect.

The connectivity part of my project is very similar to the example BLE_p2p_server, the device start advertising and when I connect to it with the mobile app ST BLE TOOLBOX the connection fail, in wireshark I see the master device is sending LL_FEATURE_REQ but the device doesn't respond.

Can you please help me as I'm stuck for a week now?

I share with you the wireshark logs (remove the .csv extension)

MCU : STM32WB55

Stack: stm32wb5x_BLE_Stack_full_fw.bin v 1.13.1

Thanks by advance for the help.

Hello,

For the disconnection, the value 8 means Connection timeout and for return error of aci_gatt_update_char_value, the value 96 means Invalid handle. Maybe, you have a wrong configuration for the role, so the aci_gap_init isn't executed, check your configuration in ble_conf.h file.

Best Regards

Hello,

The reason 0x3E means Connection Failed to be Established so it's difficult to understand your issue.

Which version of Android or IOS are you using ? And which version of ST BLE Toolbox are you using ? Can you check that you have the latest version please ?

Can you try to perform BLE Air trace to understand the reason of the disconnection ?

Best Regards

Hello,

I use:

  • HUAWEI P20 android 8.0.0
  • xiaomi MI A2 android 10

ST BLE ToolBox v 1.2.1, on the 2 phones, it's the last version as I know.

I attached the wireshark logs, remove the extension ".txt" added to be abble to upload the file.

In this test I tried multiple times the connection, as you can see the app logs below, the first 5 tries failed with reason 8 then switched to reason 0x3E, After the 3 first tests I reset the device.

I used for this test the Xiaomi phone.

Resolved by setting CFG_BLE_LSE_SOURCE to 1 in app_conf.h

Do you have more explanation?
