I am using a UART interrupt to receive a character at a time to fill up a buffer. I am attempting to put the device in low power mode using the UTIL_SEQ_Idle function inside of UTIL_SEQ_Run(UTIL_SEQ_DEFAULT). When the idle function is commented out, ...

I used a similar approach using LPUART and was facing the same wakeup issues. The LPUART is not active so the interrupt routine is not called. We can't miss any data or change how the transmitting device can send data, so our options seem to be using...

Hi Sarra, I am working on this issue with Sid. Here is the config we have at the moment after testing and trying to find what the issue might be.//Register bit control - enabling wakeup and clock for UART, not sure if this is doing anythingRCC->CR |=...

Are there any workarounds available for achieving low power mode? Using the HAL functions brings me to 5mA. The documentation I found mention that the current draw should be in uA.

I have tried using the HAL Functions provided for STOP mode and am still not able to get the UART to wake up from sleep. I have experimented with using LPUART as well. Below is how I have attempted to implement the low power/wake up functionality.mai...
