Task Management in STM32WL55JC MPU. I created task to send data to server via gateway for every 60 seconds ,after triggering task in between if i executes LoRaWAN_init() again then task not triggered again, why?

What are the Effects of LoRaWAN_init() on our task?For more- I am not register task again?Pls help i have already spend two days on that

Resolved! STM32WB, How to catch execute write event ?

I have configured my stm32wb as a BLE server and I would like to write large data. I handle prepare write request properly but how I manage the end of the transfer ?As show on the figure, the client send a execute write request but how can I catch th...

STM32WB55（BLE） My board is server, USB dongle is client. I collect data from ADS1299 through P2P BLE.However, the data often wraps, and the starting data is after a few digits.

The beginning of my data is 0xc0 0x00 0x00. I notify every 15 bytes of data on the server side, and I also receive 15 bytes of data on the client side. Then I wrap and start from scratch. The beginning of each line of data I input through the USB don...

Resolved! Is it possible to measure one component on a development board?

Hello Everyone,Currently, I am working with the board Nucleo-WL55JC1. I wonder if it is possible to isolate and measure either current or voltage of a component (RF or a peripheral for example) on my development board?. My main goal is to seperately ...

Resolved! Timer Output turns back on after ARR reload in one pulse PWM mode?

I have been developing embedded software for on and off for 15 years, and STM32 for 5. I have a pretty simple goal for a timer application on the WB55 microcontroller, and I've been banging my head for the last 2 days with little success, so I'm ask...

Any program that I generate using STM32CubeIDE for the STM32WB with BLE enabled hangs until I comment out the following line. What needs to change in the initialization sequence? /** * We should never end up in this case * However, if due to any...

the VR_PA voltage is smaller than 3.1V in HP configuration

Hi,I designed the hardware like the firgure below,my schematic below,the VDD connected to the VDDPA pin.VR_PA voltage is 1.7 - 1.9V.when Lora transmit the VR_PA voltage is smaller than 3.1V.Please support me. Thank you very much

Resolved! Any detailed manuals to look for settings in .ioc file if using HAL functions?

I am relatively new to stm32 and willing to know whether there are any detailed description for utilizing HAL functions. Recently, I'm DIYing a breathing LED (PWM sweeping from 0% to 100% and then go back to 0%) with stm32wb55rg on a nucleo board, wi...
