Hi ,
Sorry that i miss something , you are using 868MHZ but not 915MHZ ,so you need to change the firmware first .
You can download the firmware by click here and open the sketch and change the following code at “Config.c”
EEPROM.write(CONFIG_CONFIG_ID,0x00);
change to
EEPROM.write(CONFIG_CONFIG_ID,0x03);
There is 6 kind of configs you can choose that you can know it from the datasheet of RFbee .
Deray
