Please help me.
I have bought rfbee 433mhz and when i connect with xctu, it cannot define the firmware version and modem type.
The problem is at the terminal when i enter the 'Terminal' tab to enter the AT Command Mode. I send the 3-character command sequence '+++' and the RFBEE module should response 'OK' but its turn out to be ERROR when i enter the single characters '+'.
Another question is at the arduino, when i enter the serial monitor and send AT+RX, it response with
OK+B9600
OK+RC001
OK+RP:-01dBm
OK+ FU3
Why its response with -01dBm, it should come up with +20dBm isnt it? How can i change it to 20dBm?
