Hello @Leo_korbee and @pallago,
I am working on a project similar to yours, I am building a LoRaWan node with a stm32f103c8t6 bluepill and rfm95, I use the MCCI_LoRaWAN_LMIC_library library with the ttn-abp example, I am trying to add a push button that does the function to send an uplink every time I press the button, instead of each TX_INTERVAL, but I have not obtained success, could you guide me or share an example that may be of help to me,
thanks in advance.
