Wireless modules - help with code not working

[tasmod]

Following on from the thread where I asked re simple setup I bought the modules from Ciseco.

I've made up a board based on the schematic below and also some code, however it doesn't work. I have made a small test code just to get the module to transmit but no joy.

I can see on the scope that the pic sends the serout at 1 second intervals but I can't seem to get the module to transmit.

Factory default according to the site is 9600baud in transparent serial mode. The modules are the ARF version from Ciseco as per previous thread.

I've tried serout and serout2.

Can anyone see what the problem may be ?

'
INCLUDE "ALLDIGITAL.pbp"
Include "modedefs.bas" 
DEFINE OSC 10


TRISA=$00001000
CMCON=7


TESTBIT VAR BYTE


TESTBIT = 1


TEST:
    SEROUT PortA.2,N9600,["BOB",TESTBIT] '9600bps
    PAUSE 1000
    GOTO TEST

    
END

In the example I have the module input pin incorrect.

I've tried the other pin and still no success.

Does it need a short delay before the first transmission?

No need for pull-up or down resistors on lines?

(Just throwing ideas,)

Hi Robert,

Thanks for the ideas.

I incorporated a start delay in one version of the code but it made no difference.

It's all at 3.3v. According to code samples on Ciseco forum it should work with direct connection but i did wonder about this myself.
Maybe I'll try them. Documentation is sparse and confusing.

I wrote a routine that cycled through all the baud rates available, one by one, per second, but the module just didn't transmit. I watched the module input pin signals on a scope and could see the pic output arriving every second, so the code worked.

I've just received an account email for Ciseco forum activation and have posted on their forum regarding the problem. They only offer support via the forum.

Did you try HSEROUT?

Thanks Dick,

Tried that but no luck.

Seems from info from the user forum that they are faulty.

I can see signal applied to module from pic but there's no output, the main module is clocking but the rf output part isn't responding.
