Note:
1 It is recommended to purchase more than 2 modules with the same frequency.
2 Please remove the jumper cap when using
First time use:
1 Remove the M0 jumper (very important)
2 Connect the antenna
3 Connect the DC 12V/24V power supply
4 Perform data transmission and reception test at baud rate 9600/N/8/1.
