Receive uplinks & downlinks

MrKoppot opened this issue · 1 comments

Hi All,

Is it possible to receive uplink and downlink packets simultaneously with the SX1301?

I have read "Receive unfiltered LoRa Frames", issue 29 in the lora_gateway git, and "LoRaWAN Gateway as a Repeater" issue #80 in the packet_forwarder git, as well as the SX1301 datasheet.

From reading these, I know it is possible to receive either/or by setting the IQ inversion settings appropriately.
My question is: there are two radios used for Rx inside the SX1301, can one be set to listen for uplinks and the other for downlinks? I get the feeling the preamble detection that filters unwanted uplink (or downlink) packets is done with both Rx streams together- with no ability to separate them.

I have tried reading through loragw_reg.h/.c, but there is little to no explanation for what the registers do. Is there a resource that explains the registers anywhere?

Thank you for any help in advance.

Thank you for your inquiry.
