Hi Glen, I tried using the multi-threaded variant, but no luck.. seems like a low level socket exception brings down the connectivity and is not recovered until a reset is done.. Cheers! Ganesh

Hi Jason, I had done only some cosmetic changes to the code, but not really towards refining it. Since the functions were working fine, I have been too lazy to work on it (thats the curse of prototype code, remains a prototype). If you just need the basic functio of transmit/recieve and you are happy to set the parameters in the library code then you could put it to use wihtout much worries. The trouble with creating a generic library is that it needs to be tested out. Cheers Ganesh

Hi James, It should work with the jeelabs node (it is basically the RFM12B on a nice board). I have not tried it, but my gut feeling is that it should work without problems. Let me know how it went if you try it out. Cheers Ganesh

Hi Mike, I have attached the current library. It is not finished - at the moment i am trying to find the settings for highest speed and also for highest range. With the configuration set now, you can achieve 5388 bps and range of approx 25m in a normal home enviroment (incl. a wall in between). So far, I am happy with it. I would have loved to see higher speeds working but then the limitation is the SPI module in netduino (not the spi clock rate, but the lag between two consequetive write operations - the RFM expects all bytes to be clocked in within the net baudrate period. you can have higher speeds but with smaller payload. Since the overhead bytes of preamble, sync and crc is already 9 bytes, it does not make sense to transmit less that 16 bytes just to achieve speeds higher than 5338 bps). I will refine the library with some property accessors etc. and then post the final version again. Meanwhile if you have any suggestions or comments please let me know. There is a nice tool to calculate the commands: Regards Ganesh

Hi Corey, Yes..C# lulled me into coding irresponsibly :rolleyes: I changed the code so that a pre-defined string[] was used in the loop. This of course solved the problem. Cheers Ganesh
