Hello, We are facing issue of missing downlinks, say missing 5 out of 30 downlinks, there is only 1 device and 1 gateway on TTN, gateway shows data that it sends downlink, but device unable to get it.If there is fast External Interrupts (use to count...

Working with FreeRTOS in low power tickless mode for long stop periods

I'm using FreeRTOS in an STM32WL55 based application that needs to be active only few time per day (3-6).The system need to be in stop mode for most of the time and I have an external line that is connected to the LPTIM and based on this line status ...

Resolved! Is the BLE_OTA application which is written for stack V1.8 compatible with stack 1.13.0?

Hi everyone, I have the STM32WB55 MCU. The Bluetooth stack is V1.13.0. I know it has its own BLE_Ota application for this version but I wonder if it's possible to use the BLE_Ota application which is written for V1.8 on stack V1.13. So, Is the BLE_OT...

Resolved! porting project from STM32WL55JC (3.3V) to STM32WLE5CC (1.18V) - all running but no RF signal on Tx

Hi all,I have to port a working LoRa project from STM32WL55JC (3.3V) to STM32WLE5CC. First besides the JC (BGA) has more pins thatn the E5CC (QFN), anything else should be the same (expect maiy EXTI which te project does not use).Now my the issue: Th...

Documentation of STM32WB Bluetooth® Low Energy (BLE) wireless interface

I'm trying to find a proper documentation for the ACI commands of the bluetooth stack included in the STM32CubeWB MCU Firmware Package. We're running the stm32wb5x_BLE_Stack_full_fw on one CPU of a WB55 and our application on the other. Our applicati...

How can we access PB0 alternate function RF_TX_MOD_EXT_PA to control external RF power amplifier?

Hi,I need a way to control external power amplifier enable to turn it on only when transmitting.I read that PB0 has alternate function intended for this (RF_TX_MOD_EXT_PA).Can I use this function to control the external amplifier SKY66118-11? This is...
