6. Usage
Here we show two RF Pro Grove units mutually transmitting/receiving data. You need two RF Pro
Grove units and two Seeeduino to do the demo.
 Connect one Grove - Serial RF Pro to UART of Grove - Base Shield and plug Grove - Base
Shield into Seeeduino.
 Connect another Grove - Serial RF Pro to Seeeduino using the same method.
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.
 Connect CON pin to LOW/GND to enter configure mode.
 Send command to modify and query the config of the module. Config & Inquiry instruction
description see Reference.
The Config instruction format is as AA+FA+[instruction]+[parameter]. The instruction is 1 byte, the
parameter is the HEX data of 0-4 bytes (in big-endian ordering, with the high byte before the low
byte).
Note:
1) Do remember the UART transfer speed (default is 9600, better not change) if you make some
