Gateway does not send downlink to APB device

[Samuel-ZDM]

Hello, I'm trying to send a downlink message to APB devices. I configured my gateway for US902_928. The downlink to TTN must be SF9, but the terminal shows SF12. The file configGway.h has _RX2_SF 9, as it should be.

Terminal:

sendPacket:: token=1536, {"txpk":{"imme":false,"tmst":407270414,"freq":923.3,"rfch":0,"powe":20,"modu":"LORA","datr":"SF12BW500","codr":"4/5","ipol":true,"size":22,"ncrc":true,"data":"YMgXAyaKBQADQAIAcQM1AP8BZUMRKg=="}}

txLoraModem:: end=micr=309.606519, tmst=309.606678, wait=159, freq=923.299, sf=12, bw=244, powe=15, crc=0, imme=0, iiq=40, prea=8, rfch=0, ncrc=1, size=22, strict=1, a=26:03:17:c8:, size=22, data

Hi Samuel,

I see that you are right. The software (even very close to the hardware) says that the downlink is complete and I even receive an interrupt TXDONE. However I see that not all is transmitted.

The latest version 6.2.7 does include separate uplink and downlink monitoring/website. If you see what;s going wrong please tell me.

Thank you.

I'll do the tests, when I finish I give you feedback.

It's still not working. I took a test now and no messages are received. Even if the SF problem is different. When I look for this variable _RX2_SF, I don't find it being used anywhere. Perhaps the value of the SF downlink is not being changed.

Thank you!

In my case the Downlink frequency is wrong, I'm searching where to correct it, anyone found another issue to this?

Thanks!

I have corrected frequency in json file which will also solve the problem with downlink. I created a pull request from my fork.

I correct reconfiguring the gateway for my region because in Brazil we use AU915 instead of US915.

Best, thanks for all!
