Was anybody able to implement a custom BLE profile for the STM32WB55?

Was anybody able to implement a custom BLE profile for the STM32WB55 using STM32CubeIDE v1.7 (or around) and the firmware package 1.11.1 (or around)? I would like to recreate and make publicly available this workshop. It is out-of-date.

STM32WB BLE Beacon scanner

I want to use an STM32WB module as a ble beacon receiver/detector so I can monitor beacons on my PC using a uart or USB vcom? Are there any examples that can help me and if "Yes" where can I find them?

Is there a really simple STM32WB example?

All examples of the github repo are at least a few 10 of thousands lines of code big.I just want to share a few bytes of information over ble. Is there a really simple example without timeserver, freertos and that kind of stuff?Just like:start CPU2in...

Resolved! SRAM2a retention in Standby not working on STM32WB55

Hi,I'm trying to make SRAM2a retention in standby mode work on my STM32WB55 device.As far as I can tell, the device enters and gets out of Standby as expected (the C1SBF and C2SBF flags are appropriately set when the MCU get sout of the low power st...

Resolved! Will Nucleo-WL55JC2 modules work on gateways configured for US915?

We accidentally bought a few Nucleo-WL55JC2 modules whereas we really wanted Nucleo-WL55JC1 modules. My understanding is that the JC2s are intended for AS433 applications. I would have expected the join to be unseccessful, though. However, we succe...

the user button code is not working on NUCLEO-WB55RG

I am trying to use the pushbutton of NUCLEO-WB55RG and I tried coding it in both external interrupts and also as a gpio input. The pin configuration is correct. The same code is running on other Nucleo boards such as L496 and L432. But the code does ...

How to transmit the 247 data in stm32wb?

I have configured the stm32wb with 247 data transmission but in the receiver side the buffer seems like it transferred only 20 bytes in the notification. For note: The values are updated in the 255 sized cmd_buffer in the aci_gatt_update_char_value(...

Starting FUS with jtag seems to break the JTAG connection. Is there a way to handle this?

I am developing a bootloader where it must install a new stack using the FUS (STM32WBxx). When I am debugging and I call into CPU2 to start the FUS, the JTAG loses connection and will not reconnect until I reset everything. Is there a way to handle...

STM32WLE timing between OTAA request and gateway response

Hi All,I'm creating a TTN application using a STM32WLE5JC. After configuring the LoRaWAN application in STM32CubeIDE I have been able to send an OTAA join request to a gateway using the credentials provided by the TTN application. I can see the join ...

How sequencer works in stm32wb

I don't understand if a function that you have set in the sequencer goes out of the sequencer once it has been executed or you have to do it with code. I have read AN5289 and I didn't find out the answer. Thanks in advance.
