    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.
