I have a WiFiRedback which is made up of Wifi (MRF24WBOMA Microchip) and Nano CPU.

Is there a recommendation of how to hibernate and/or sleep both the wifi and the nano ?

The power drain of 100ma is way too much for a battery operated WiFiRedback.

Should this question be asked in the Microcontroller section ?

It should contain a link to the device(s) in question, at the very least.

Jerry,

From the schematic at http://ruggedcircuits.com/AM040/am040.pdf, it seems that the Hibernate (pin 20) of the Microchip WiFi module IS connected to the Atmega328 onboard, and it seems it is connected to D8. Try something like:

Code: [Select]

    pinMode (8, OUTPUT);
    digitalWrite (8, HIGH);


to Hibernate the WiFi, and:

Code: [Select]

    digitalWrite (8, LOW);


to wake it up. Let us know how did the module behave.
