• AT+TXTESTMODE = 1
CW_MODE Mode // Send out an un-modulated carrier for 30 seconds
The CW Test Mode command requests the device to enter the CW test mode. This will cause the device to output a CW
signal for 30 seconds after which it will turn off the RF output and return to sleep mode.
• Send Test Packet (0x02)
AT+TXTESTMODE = 2
TEST_PACKET Mode // Send out a single 9-byte test packet
The Send Test Packet command requests the device to transmit a single test packet. This test packet consists of the
following payload: 0x80AAFOFOFOAAFOFOFO
• Modulation Test Mode (0xFC 0x03)
AT+TXTESTMODE = 3
3 = MOD_MODE // Send out a modulated carrier for 30 seconds
The Modulation Test Mode command requests the device to enter the Modulation test mode. This will cause the device to output
back-to-back test packets continuously for 30 seconds after which it will turn off the RF output and return to sleep mode.
