Hi Guys
i have one Moteino as receiver and one Arduino pro mini as sender. the sender is powered up with a battery on it and the receiver has connected to my laptop to power up
i want to bring the sender in sleep mode, when the receiver is not on
in fact i need , my sender listen for example every minute, when my receiver is not on
and when the receiver is on, the receiver send something to sender, so that , the sender understand the receiver is on and start to send the data
but i dont know how
the both of them are able to receive and send data
i am searching for a solution for my problem
i really thank you to some one, who help me
in following are my receiver and sender code:
receiver code:
// Sample RFM69 receiver/gateway sketch, with ACK and optional encryption, and Automatic Transmission Control
// Passes through any wireless received messages to the serial port & responds to ACKs
// It also looks for an onboard FLASH chip, if present
