I have a project where I will have payload data of GPS float values (coordinates), time and a single digit integer. Any way to my question. I have read Robert Faludi's excellent book "Building Wireless Sensor Networks". He talks about S1,S2 radios and I am not sure how much of the S3B Digimesh radios differ. Referancing the XBee manual for the radio I came across a question on the transmit options. at offset 16 the digimesh option is b'11. I am not sure how to interpret this.
The next part of this question is the use of union to break down a float number (the coordinates). Offset 17 to 24 is the space I have for data transmission. 5110.9000 and 11430.1923 needs to be broken down. How many bites will this take up in the RF Data frame?
Thanks for you time in pointing me in the right direction. Bryan
