Resolved! BLE Remote using STM32WB55

Hello,I'm working on a BLE Key Fob with 4 buttons operating on a CR2032 coin-cell battery. The goal is that the device sends a "key pressed" data with the status of all the buttons and the battery voltage a short time of period (a couple of seconds),...

Resolved! Significant osDelay Extension (10x Longer Than Set) in STM32WBA55 Running FreeRTOS+BLE

When using the NUCLEO-WBA55CG development board and running the BLE_HeartRateFreeRTOS example, I found that the delay time of osDelay is extremely long, nearly 10 times longer than the set delay time. What is the cause of this and are there any solut...

NVM Storing Issues

Hello,Sometimes saving to flash takes the devices a couple of seconds.It enters through APP_ZIGBEE_persist_save() -> APP_ZIGBEE_NVM_Write() -> EE_Write -> EE_Transfer -> EE_ReadEl; and takes a while in this function.Occasionally, the device enters th...

Resolved! How to start broadcasting BLE using the p2p server example after disconnection.

Hey,I am trying to make a device which connect to an app using stm32wb15. Everything works properly, but I want to make it so that when the device becomes disconnected, i can use a button to broadcast BLE so that i can connect through an app again. I...

Resolved! STM32WB1MMCH6TR very low BLE range

Hello! I'm working on a custom PCB that uses the STM32WB1MMCH6TR module, which was chosen specifically because of its integrated antenna. Unfortunately, with the first prototypes I'm getting extremely poor range with BLE, usually <-80 dBm even just a...

How to save USART messages?

Hello,I have STM32-WBA55CG connect with MEMS sensor. STM32 board will send the messages back to terminal through USART. The WBA55CG is right now connected to stationary power source. It would be nice if someone can give some ideas, how to transform i...
