Immediately disconnecting after connecting to STM32WB5MMGH

[mnoro.1]

I am trying to immigrate my project on STM32WB55RGV to STM32WB5MMGH. Now I am using last firmware package V1.13.3 instead of 1.10.0 that used for STM32WB55RGV.

I updated FUS (FUS V1.2.0) and BLE_stack_full_fw.

I am trying to connect STM32WB55RGV but immediately after establishment of connection I am receiving disconnection event (HCI_DISCONNECTION_COMPLETE_EVT_CODE).

How I can fix this problem?

Can anyone help?

Update: I ran a firmware in debug mode and saw below line not executed under the case HCI_DISCONNECTION_COMPLETE_EVT_CODE

disconnection_complete_event = (hci_disconnection_complete_event_rp0 *) event_pckt->data;

as a result I cannot understand reason of disconnection!

Hello,

If you retry with BLE Full Stack v1.10.0, does your application work ? Are you able to see the debug trace "DISCONNECTION EVENT WITH CLIENT" in your terminal ?

In order to understand the reason of the disconnection, place a breakpoint on the case HCI_DISCONNECTION_COMPLETE_EVT_CODE and do step by step debug.

Best Regards
