hi we developed our own RF protocol based on the free S.N.A.P i think is to big to fit in a pic it was designed to run on avr mega 323 and mega 128 the latter being for a pc link and the 323 used for a handheld monitor unit and a loadcell telemetry unit.
it uses a low level hard ware driver so we could drop

I have used this PLM in the past. You can implement snap protocol to communicate the devices. In my case I used a HDLC implementation. Here I have attached a document about snap. Regards.

I developed a wireless network to environment monitoring using snap... But I had to do few modifications to improve the performance of the entire system...
I´ve chosen snap after looking many others protocols...
Let me know your application and I can suggest something more...

I do, quite simply, by waiting a certain period of time to allow the line to settle. In my case the network consists of 32 units, all talking asyncronously.
Take a look at snap protocol. It's free.
I use my own protocol but snap looks good.

Have a look at ST7536,ST7537,ST7538 on ST website, you will also find app notes with schematics/source code.
HTH have info about the snap protocol, commonly used in these analogue modems.
I think ST are the only company left doing analogue modems, most are now looking at dsp based systems for higher data rates.

I'm hesitating between the Modbus and the snap protocols.
Which one is better and why? I personally prefer snap,
because it looks easy to implement and it has lots of
examples for BS1 and BS2, which can be easily adapted
for Picbasic pro. But as I can see, most of the users
in this forum are commenting Modbus. Are there any (...)
