Sending data from Xbee end device in sleep mode

0 votes
I am using XBee series 2 module for communication between arduino and computer. I have coordinator attached with computer and an end device with arduino. I want to send data from arduino after every 1 min. But the problem is i am using cyclic sleep mode on end device with ST (time before sleep = 5 sec which is default value). I first send data as soon as module is on which works fine.But then after 5 sec module enters in sleep mode. Then after 1 min i am unable to send data to computer. In fact my end device module does not communicate with arduino either. Any idea how to awake sleeping module?

You must use hardware flow control to know when the radio is awake or in a sleeping state. You should also adjust the SP and ST times on the module to your desired sleep and wake periods.
