Hi All, In my application, I am using a radio module for wireless transmission.. When power is down, the data should be written in flash and on power up data should be read from flash and transmitted. PMM module is configured to detect power level fall.But when PMM module is enabled, the radio module fails to transmit data and I am not able to record the data in flash. The supply voltage of radio module is 2.8-3.4 V and its Tx Current is 45mA (@ 3.3V) and Rx Current is 50mA (@ 3.3V). Please guide me how can I solve this. Thanks in advance. Regards, Dhara
