Here DA14531 is used as the Slave device to receive data from sensor, where i used non connectable format to receive and broadcast the data. But while using renesas flash, i didnt above small peak between two advertising events, if i change other flash make like Macronix , i observed a small peak, which i dont want. if this remains, power consumption will be unexpected. so help me to the issue.
