I am running the same firmware build on two different pieces of hardware that contain an STM32WB55CG. The firmware is configured to use a Fixed Pin for pairing and bonding. One works as expected and will create a bonded, authenticated, encrypted link...

I am using an STM32WB55CG in a slightly challenging environment. aci_gatt_update_char_value() works great most of the time and returns BLE_STATUS_SUCCESS and transmits data. Occasionally the STM32WB55CG will disconnect and then reconnect. Our applica...

I built the project with CubeMX 6.2.1. I have added the call in main to the sequencer. I have added the sequencer header file. I have added the IPCC IRQHandler functions to stm32wbxx_it.c.The project builds fine and downloads to the NUCLE0 WB55. It s...

Here is the function running in my STM32WB55CG:/** * this function can be nested */ void UTIL_SEQ_WaitEvt( UTIL_SEQ_bm_t evt_id_bm ) { UTIL_SEQ_bm_t event_waited_id_backup; UTIL_SEQ_bm_t current_task_id_bm; /** store in local the current_t...

We are currently running 1.11. We have some units that will pair reliably but others that will not. We've pushed this aside to work on other issues temporarily and hope to get back to it soon.

Hey Remi,Thanks for the reply. Yes both connect without pairing. Yes both boards are exactly the same and loaded with the same application SW.They are both attempting to connect to an nRF application on my PC via an nRF52840-Dongle. One works reliabl...

The problem is not that our unit occasionally disconnects. The problem is that it does not reconnect smoothly every time. When this disconnect/reconnect occurs we recover without issue most of the time (the vast majority of the time). But, when we ge...

CubeMX 6.2.1 takes care of the IPCC functions that used to require being added buy hand: We also needed to make sure that we were using LSE for the RF system wakeup:After making these changes, everything works as expected.

@Christophe Arnal, if I make change these values from what is generated by CubeMX, I don't see anything on UART1 TX.Do I also need to make the following changes (particularly setting CFG_DEBUG_BLE_TRACE 1):/***************************************...

CubeMX for BLE projects only allows the Device Information Service to be included in projects with BT Heart Rate Sensor Enabled. Shouldn't this be allowed to be included in all projects?

Fixed Pin Pairing and Bonding with an STM32WB55

aci_gatt_update_char_value() returns success but no notification is sent.

How do I build a simple Nucleo WB55 project that advertises and connects with CubeMX 6.2.1?

During startup I occasionally get stuck in the function UTIL_SEQ_WaitEvt located in STM32_seq.c.
