Using concentrator to sniff GW <-> DEVICE traffic

Semtech Gateways SX1301
#1

Hello,
i’m checking for a solution to perform a traffic gw-device sniffer. Starting from loraGw HAl library 5.0.1 i’m thinking to modify the packet logger utility in some way. The main problem is I/Q polarity inversion related , i mean i don’t kow if sx1257 radio front end can be configured in order to receive with I/Q polarity inversion so that will be able to receive GW downlink. So if this kind of configuration were possible a concentrator could be used as a sniffer of others GW - Device traffic.
What do you think about ? can SX1257 programmed as above ?
Thanks in advance
B/R
