I stuck at RF communication between 2 arduino for several days
RX always tell me that RX recieved nothing (-1)
I experiment several things.
1. is it NewSoftSerial's fault?
I don't think so,
because when I wire the Reciever's RX pin and Tranciever's TX pin,
both of two can communicate very well
RX recieve 255 when sending 255 in TX side.
2. is it RF module's fault?
when TX module's Data In pin is connected logical HIGH,
RX Module's Data Out pin is cycling among logical 1, 1, 0, 0, 1, 1, 0, 0...
so.. I don't think so
3. is it power supply issue?
I connect both of TX and RX to 5v which is streamming from arduino UNO, Pro mini respectively
and product info says TX's and RX's voltage range is 3~12v, 4.5~5.5v respectively
4. is it source code problem?
TX side code is here
and RX side code is here
NewSoftSerial RF = NewSoftSerial(14,11);//RX,TX
5. is it antenna issue?
product info says it's ok to connect antenna 30~35cm long
and I connect it as like it(though it is just wire)
could somebody help me?
I attach the arduino UNO and Pro mini's picture as well
(since someone says that my question is too vague and unreadable,
I try write it down as readable as I can,
but I am a beginner, so it could be still vague and unreadable,
if you point my writing mistake out(instead of just saying "it's too vague"), it would be greatly helpful)
thanks for reading
