Resolved! BLE server without LSE crystal as clock error. Working on WB55 board but not a custom board

I am trying to setup a ble server on a stm32 board that does not have a lse crystal. I have followed the normal steps and the steps that use the hse crystal instead (https://community.st.com/s/article/configuring-stm32wb-for-bluetooth-le-without-an-l...

Setting the Server ID for my BLE server

I have a BLE server derived from the STM provided BLE examples. The server ID that it generates is 00012002FF77. How is this generated? I can't find it anywhere in the code. Should each of my devices use the same ID or should they each generate uniqu...

For the BLE_DataThroughput example, in dts.c, when receiving an event of EVT_BLUE_GATT_ATTRIBUTE_MODIFIED and trying to find out which characteristic is the one being modified, why do the handles have an integer added to them prior to the comparison?

The code in question is below. You can see that each of the characteristic handles have an integer added to them prior to the comparison (i.e., + 2, + 5, +1). Why? case EVT_BLUE_GATT_ATTRIBUTE_MODIFIED: { attribute_modified = (aci_g...

How to use open bootloader on the STM32WB serie

Hi, I would like to use OpenBootloader on my STM32WB35 but I do not find any exemple about it. There is a repository on the official STM github but it is empty : Maybe somebody from STM can correct this :) I already checked the STM32Wb package and t...

How to predict how many nodes in the zigbee network?

I know there is no simple answer to the above question. It depends on how many packets my network is sending. Maybe there is a formula predicting the number of nodes in the network where I know what data is sent and how often. I want to know if my ne...

Suggestions on how to implement firmware upgrade on STM32WB55

Hello everyone,I'm migrating a code base from the STM32L475 to the STM32WB55. The WB55 was selected due to availability and it's not expected to use the connectivity features (BLE, ZigBee, etc.) it has.Looking at the OTA firmware upgrade examples for...
