The TB387 high powered module (HCMODU0089) provides a means of transmitting serial data over much greater ranges than standard RF modules such as Bluetooth. Simply connect a TTL serial interface to a transmitter and receiver module and the modules will transparently transmit your data over a 2.4GHz signal at a range of up to 400 meters. In practice we have successfully transmitted single byte data in free air in excess of this. The module can also be placed into a configuration (AT) mode and using simple ASCII 'AT' commands sent via its serial port its default parameters can be changed. This includes changing its frequency to one of 80 channels or its two byte ID which allows a theoretical 65536 modules to communicate with each other. To try and reduce errors caused by poor reception an automatic retry system is enabled (defaults to 100 retries) which will repeatedly resend a data packet a fixed number of times.
