Hello,
How can I synchronize the wireless nodes (one nRF24LE1 on it) in a real-time wireless sensor network? I use nRF24LE1 as the transceiver and receiver.
Thanks.
Easy task, and long way..
I need to counting/measuring time how long time 220V line was on-line (assumed all time after install).
I've tried to find ready-work chip FR-transmit...
hello I'm Mehdi. i work on two NRF24lL01 wireless modules. I have a doubt that this modules can be damaged or not work correctly. because the module don't give external interrupt...
