Due to the certification and test procedure of new equipment, we have to enable a continuous transmission mode on the BG95-M3 module. We are currently using the Transmit in FTM (AT+QRFTEST) command found in the BG95 FTM Application Note.
When using the commands for GSM, we see a constant modulated waveform on the spectrum analyzer. However, when using the commands for LTE-M or NB-IoT we do not see any modulated waveform on the spectrum analyzer.
AT+QRFTESTMODE?
AT+QRFTESTMODE: 1
OK
AT+QRFTEST="LTE BAND4",19950,"ON",100,1,0,1,127,4,0
ALL ON
OK
Are there any AT Commands supported on the Quectel BG95 Module that supports constant modulated carrier for NB-IoT?
