Transmitting at 1.5x requested frequency? #52

Closed MTMichaelB closed 1 year ago

MTMichaelB commented 2 years ago

I'm the electrical engineer on a project. As part of EMC testing, we found that for the first time after our system boots up, when I use test_loragw_hal_tx to transmit, it transmits at the requested frequency as well as at 1.5x the requested frequency. If I Ctrl+C kill the process and start it again, the 1.5x frequency isn't there anymore. Continued repeats of the command also do not send the 1.5x frequency. If I warm reboot the system, the 1.5x frequency comes back for the first run of the command.

I'm using this command to transmit rather continuously: ./test_loragw_hal_tx -f 925.1 -r 1250 -m LORA -n 10000 -s 12 -b 500 -z 255 --pwid 16 -l 65535 -t 50

We are using release v2.0.1.

Does this sound like an issue that others have seen?

Thank you.

I am unable to reproduce this on my SX1302CSS915GW1. Could you share the concentrator board number or the product?
