How do you control Digital I/O to power up the NRF24L01

[Phil Whitmarsh]

Hi,
I have a development board that i designed for an Arduino Pro Mini
It runs from a Lithium battery i.e. about 3.7 to 4.2v
I have use this board for various projects, it has a 433Mhz Tx board an NRF24L01, a few i2c ports 3v3 & 5v, it has a switched power source (P-Channel Fet) for my sensors that are on the i2c port.
So i have now come across the Mysensors site and decided to have a try.
It works fine if i permenantly supply power to the sensors and the NRF24L01, but i cannot get it to switch my P-Channel Fet that controls power for the sensors and the NRF24L01.
I did read that you have set set the digital I/O for the AVR up in the presentation section, which i have tried.

Any clues or pointers please?

Thanks,

Phil.

Fixed -

You have to use void before() and place it before void presentation()

void before() {
pinMode (4, OUTPUT);
digitalWrite(4, HIGH);
}

void presentation()
{
// Send the Sketch Version Information to the Gateway
Serial.print("Send Sketch Info: ");
sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);
Serial.print(SKETCH_NAME);
Serial.println(SKETCH_VERSION);
wait(LONG_WAIT);
