RN4871 sleep mode : dormantMode not exists

Hi,

I want to reduce current energy used by Sodaq Explorer.
For that, I want to put the RN4871 Bluetooth Module in sleep mode. So, in the setup, I put this code :

  //RN4871 Bluetooth
  rn487xBle.hwInit();
  bleSerial.begin(rn487xBle.getDefaultBaudRate());
  rn487xBle.initBleStream(&bleSerial);

  // Enter dormant mode 
  rn487xBle.enterCommandMode();
  rn487xBle.dormantMode();  
  bleSerial.end();

When I compile, I have this error :

The Microchip_RN487x (1.0.3) is well installed.

Does someone have a solution?

Thank you in advance :slight_smile:
