Hey I am using RKI-1197 2.4Ghz module with AT89c51 controller and i am connecting tx pin of controller with direct tx pin of module and rx pin of reciever module to direct rx pin of controller and still i am not getting desired o\p at reciever end which i am sending at transmitting end . Do i need any special coding for compatibility of 2.4Ghz module with controller or any special hardwere for configuration? Please reply ASAP , and Thanx in Advance.
Dear i have connected as per datasheet that TX pin of controller to the RX of module and vice-versa , though i am not getting the desired output and i have checked the modules individually by on CRO . I think i have read somewhere that it requires kind of "MANCHESTER CODING" for better result but still i don't know about that term perfectly. So could you suggest me about that or else can you send me "MANCHESTER CODING" for my understanding and for better knowing of that term...?
RF modules are not all the same by any means - You need to study the documentation for the particular module that you are actually using.
If it states that Manchester (or any other) encoding is required - then that is what you must do!
"i don't know about that term perfectly"
It is a very long-established and widely-used technique - google it!
NB: if your module does require Manchester coding, then it does not make sense to be connecting it direct to a UART!!
