Transmission works with wires but not always with wireless

[Ioannis]

So...
oneofthree = jyi1 ???

You are such a tease...!

oneofthree or jyi1 or whatever your name is (we never got any) I told you before to start one data byte at the time. A complex program is hard to debug especially if there are serial com's.

Also do not manchester encode the preambles. Only the data bytes and CRC or Checksum.

I looked back at some previous projects I have done with wireless comms. I have not used the Laipac modules, but have used the RFPICs and the Radiotronix modules.

I have used 1200 baud with one preamble, two start-of-transmission identifiers (STX), and one end-of-transmission (ETX) identifier. The packet data is between these wrappers. In my experience the manchester coding did not help much with short messages.

The only thing I was able to find was the following comments in my code:

/* for wireless link, the "invert" option should not be used
as this causes the transmitter to iddle on */

My point is, have you tried your code with T2400 (as opposed to N2400)?

The Radiotronix RCR receivers are clones of the Wenshing/Laipac receivers. The only difference is they number the pins in reverse order. I think Radiotronix gets them from Cansec in China.

T2400 doesn't really help.
