Ryan, Thank you for the response. Since I'm targeting low power I want more advice regarding the UART communication. Suppose I have to send 3 bytes through uart to get the energy meter to respond and send back 3 bytes of data, what is the best practice to do this? Is it okay to simply place the 3bytes in the transmit buffer without uisng interrrupts and use ony interrupts for receiving bytes? Also since the device has to wake up every 2 sec to count the number of interrupts for sending data every 5 mins, should I switch to a mcu with rtc?
