Hi, you can use the integrated lpm module with some extensions. I for myself implemented the STOP2 mode in app_entry.c. Any interrupt will wake the µController again and it will continue until UTIL is idle again. This includes the timer interrupts t...

In that case I just wanted to test the function as you did in the p2p-server example. Where you also sent the ACI command to change the connection interval in the HAL_GPIO_EXTI interrupt routine. To make it work you also set the that interrupt to the...
