Problem with serial communication

[Shreenu]

Please help me with the tx-rx serial communication in atmega 16A chips.
I am using 2 atmega 16A microcontroller and want to send some data and strings from one and want the other to respond according to it, but after many attempts i failed, I have a new rf module. Please help me with coding section…

r u giving direct input to Tx Rx RF modules from micro controller? it will not work

if you use MAX232 at both sides then also it will not work. because normal serial protocol is not for RF comminication. for sending data wirelessly through RF channel you need protocol like used in HT12E-HT12D chips.

Hi Shreenu,

Set the baudrate at both the side to 1200 or less than that. It should work.
