Newbie radio link issue

[George]

PBP manual, page 130 and page 137.
There's something on each of those pages that you've forgotten. Hopefully after you add that certain thing, all should be well. The rest of the code, at first glance, looks like it should be ok.

I presume you are meaning the mode names? If so i used the code instead - ie. 0 = T2400

I'll try the direct connection now - I was thinking about it, but put it off

I just looked at the PBP manual again. If you're using numbers, you don't need to include the file. My bad...
Also, the datasheet says to use inverted data, i.e. N2400 instead of T2400.
I'm just having a quick look at the datasheet now...so bear with me...

I pulled the radio modules off and did a direct connect - and it didn't work! All it was was making sure the internal oscillators were calibrated. Then it worked so my hopes were high for connecting the radio modules again - but alas, it was not to be. just doesn't work for some reason - I think it has something to do with the internal setup of the radio chips - for some reason (maybe their brand name) I thought it would be easy! And would just transmit data as it came into it's pin - but apparently u have to set baud into the receiver and there r a few other options which make it a bit complicated for a beginner.

If direct connection works and RF link does not (considering that the radios are communicating) then I would suggest to try sending only the bytes AAh repeatedly and see if the receiver gets the data.

If you have success then consider to use bi-phase or manchester encoding of the bytes to be transmited (forum has solution for this).

What's the command line to make it just send the AAh bytes repeatedly? As I said before I'm totally new to serial comms - are you meaning simply as:
SEROUT PortA.0,0,["AAh"]?

Does anyone have any recommendations as to a good radio set to use - like one where you hook it up and it works? No internal settings that are adjustable etc - just goes

[mister_e]

AAh : AA is the value, h represent Hexadecimal.

SEROUT pin, baud, [$AA,$AA,$AA,$AA,$AA, YouDataVariable]
OR
SEROUT2 pin,baud,[REP $AA\5,YourDataVariable]

Anything from Linx, Laipac, RFSolution, Maxstream will work without too much adjustment, but the manchester protocol have to be use in most case.

Sometimes just by sending some $AA, a header, your variables may work good. If you don't have many data to sent, i don't think Manchester is really needed.

Transmitter
SEROUT2 ...[REP $AA\5,"READY", YourVariable]

Receiver
SERIN2 ...[WAIT("READY),YourVariable]

[Ioannis]

Just for testing try to send repeatedly:

loop:
SEROUT pin, baud, [$AA]
goto loop

This will send endless AA to the receiver.

If you read them then you need to encode your data.

If you don't then you need to check the design back from zero.

For modules contact me private if you need many. We build our own.
