Arduino for STM32

Hello, I am currently working with a SIMCom NB-IoT modem that communicates over UART to my STM32L082KZ. When processing large downlink messages (chunks of 512bytes at a time) I run into the issue that at some point my code seems to change variables and send empty strings out (AT commands) which is k...

First, library 1.1.0 are not released officially yet. I guess you used idle or sleep mode (not deep sleep nor shutdown) as they work in __WFI. The new version can handle small sleep time than 1000ms depending of the prediv factor set. I guess also you used the core 1.9.0 that's why you don't have t...

Can anyone help? I am trying to detach/queue an external interrupt on EXTI-4 and EXTI-5, so that they do not wake the processor during a critical stop mode deepsleep time of (for example) 1340ms. During this time-out I want to go into stop mode with RTC for low power purposes. On a previous processo...
