7. LED function
8. Config Instruction
The HM-TRP add the LED function for easier debug & function demo, thus the users can easily understand
whether the module is working or not or in any other status.
1. The red and green LED will flash when there is power on if the module start working.
2. The module will be ready for Config status if ENABLE pin is low，CONFIG pin is low. It will be in
3. The red LED flash when the module is in transmission ，the red LED will be off if the transmission
4. The green LED is off when the module is in receiving status, the green led will flash once if the module
1. Instruction[F0]:
2. Instruction[E1]:
3. Instruction [D2]:
LED function:
You need to Config the parameter and inquiry for different need to realize the function. The HM-TRP can
Config and inquiry for working frequency, wireless data rate , receiving ISM bandwidth, frequency
deviation, transmission power, UART transfer baud rate & RSSI signal reading etc.
Config and Inquiry methods:
The module will be ready for Config status if ENABLE pin is low，CONFIG pin is low. It will be in Config
if the red and green LED keep lighting. Then you can Config & inquiry on the module.
The Config instruction format is as AA FA+[instruction]+[parameter].The instruction is 1 byte，the
parameter is the HEX data of 0-4 byte which the high byte before the low byte.
The instruction’s transfer speed should keeps the same as the transfer speed of UART. The instruction’s
transfer speed will change accordingly if changes the transfer speed of UART .The range of transfer speed
of the instruction is from 1.2Kbps –115.2K bps.
