Module Use
Connect the RS232 connector with PC or TLL level with MCU directly，apply power
supply and the module is ready for your application. If CONFIG pin is low at power on, module
will enter normal mode for data transmission, or enter configure mode to setup work parameters
1. Communication mode
When CONFIG is low at power on, the module enters into normal communication mode.
2.
Normal communication mode connection
The use of default setting offers data communication (the serial default setting is 9600, 8, N,
1). It can be setup via HM-TR SETUP TOOL.
When the serial data rate is less than 9600bps, the module supports continuous transmission,
the max can be over 1,000,000 bytes at a time. When the rate is more than 9600bps, it should be
less than 32 bytes at a time of transmission.
