I built as system where I used multiple TX/RX modules to transmit data. The data was encoded using AVR microcontrollers with codes I wrote myself. It seemed perfect when only 1 TX was on and it could select addresses and send data to any of the 3 respective RX modules with respect to the address sent by the TX. But when 2 TX modules was ON the RX received data from only the nearest TX module.
1. I did not use interrupt in my coding. I modified some code I saw on the net and used this checklist to make sure the address matches
2. All TX/RX modules work at the same frequency i.e 434MHz.
Is there any way i can overcome this problem through coding.?
I want to race cars using this system as the wirless control method. But I can not do so if the RX modules receive data from only the nearest TX module.
Is there any other DIY remote control methods I can use for this purpose??
Looking forward to your generous help.
If u want to see the code just knock me I'll mail it to you. or upload it here if needed.
