Overview:
TB387 is based on 2.4GHz frequency band wireless transparent data-transmission module.
Module supports most basic AT commands: baud rate, ID number, frequency settings and inquiries; factory settings; version information.
When the module is in AT module, users can use serial-port to issue AT commands to set the module\`s parameters.
When the module is in transparent data transfer mode, the user transmit data, frame number data module, add packaged rowcount, and then automatically transmit , at reliable range, the module will automatically re-transmit data to ensure successful transmission.
