Hi Joe,
I've placed 0.1uF caps on each transceiver VDD and GND pins.
Also placed a resistor on the receiver side as a pullup for the RX pin.
Still i get intermittent and incomplete data

OK, so then you are getting, some data. That's good. Does the receiver still fail to boot sometimes? If so, have you swapped the Tx/Rx modules to see if they both react that way? (SURE Electronics ) Seem like pretty easy to deal with vendors. Just in case there is hardware problems. If all of the above is TRUE, then I think you will need to reevaluate how you are sending data. You may need to add some character pacing scheme and or send data X # of times to insure reception.Originally Posted by ruijc

Are you using Tony's code exactly as published here? If not may we see what you ARE using?
EDIT: I just loaded Tony's code . . . the half that he posted into MCS for examination . . . I hope you ARE using more than that, on account of there is no place in this where data gets loaded or stored . . . so let us see your code, please.

Hi Joe,
No, so far so goodDoes the receiver still fail to boot sometimes?
Did that...well...sort of...You may need to add some character pacing scheme and or send data X # of times to insure reception.

Thanks to Joe the problem has been solved.
The problem was related with the Mode ( debug defines ) settings.
I changed from MODE 1 to MODE 0 and it started to receive all data 100%.
Thanks Joe.

Hello
can maybe sombody give a circuit so I can test it.
I have the CY2196R module but I didn't get it running also.
I hope for respons.

I was looking for things to do with my GP-GC010. I came across this forum.
I got my GP-GC010 working well. At first I was having the same problems as
ruijc was having. I got mine to work with a debug window and an example
program displaying this string "On The Air!". I'm using a 3.3 volt regulator.
I reset it and it started working (I don't really know why!).

Ah, call it the joy of electronics!

Firstly, apologies for dragging up this post yet again!
I too am having trouble with this module. I've tried everything I can think of, but I can't get anything to be received. Is anyone who has got this working prepared to help me out? There are so many contradictions and instances of vague language in the 'data sheet' that it seems amazing anyone has got this working!
I am using a PIC16F88 USART to transmit to one module and I'm reading the other with an arduino. When I send serial data to either module, the busy LED lights. Everything looks good. Pins 7 and 8 are pulled high, 5 and 2 are grounded and everything is running on 3.3V. I'm definitely running at 19200 baud rate and I'm using true rs232 (i.e. normaly high, when data sent goes low). However, I've been trying for almost a solid day now and the busy LED of the other module has never flashed in response to receiving transmission from another module.
I've tried setting the transmission frequency but the data sheet is so vague that frankly I could have been doing anything.
Any ideas? Thanks!
