I am testing the I-CUBE-LRWAN(LoRa) Pingpong sample code.
I am also testing uart interrupts.
If you do not call the LowPower_Handler function in the main loop, the uart interrupt will work fine.
However, calling the LowPower_Handler function does not work well for uart interrupts.
I tried to use UART part of 1.0.3 version of AT Slave but it is difficult to apply different structure.
Can you help me?
