HM-TRS
V2.1
The module work mode is half duplex mode. The data will be immediately transmitted as
soon as it accumulates 32 bytes in the serial port. When the data is less than 32 bytes, it will
transmit again after 30ms. If the data is required to be sent out immediately, make sure it is at least
32 bytes.
Every time it finishes transmitting, the module will automatically shift into reception mode.
The shift time is about 5ms.
In normal mode, the pin ENALBE controls the module work or sleep, module will enter
sleep mode as soon as the pin is low level.
3. Configure Mode
When CONFIG is high at power on, the module enters into configure mode. In configure mode,
the module work parameters can be setup via HM-TR setup tool on computer side and the
communication format between module and computer is fixed: 9600, 8, N, 1.
