Any developer success to run RAK831 with latest radio driver by semtech as https://github.com/Lora-net/lora_gateway? Appreciate if someone can share some update if have.
Hi Kenyu,
Yes, I have the RAK833 and the RAK831 running on the latest semtech radio driver. Many use Kersing’s multi-packet forwarder which supports the TTN protocol via MQTT and his lora gateway repo builds on top of semtech’s latest driver.
If you look at my github repo here: https://github.com/KentNetwork/lora_gateway you should see in the git history the changes I have made to the recent lora_gateway, there’s also a packet forwarder in another repo in that community. Most of the changes are the same as Kersing has made - just without the MQTT stuff, as such it is more akin to the older polypacket forwarder (just a little more up-to-date).
Is there a problem you have in particular?

appreciate your reply. Thanks. We have a internal discussion about the latest driver on RAK831. Actually, we did on RAK833 with openWRT on MTK platform. Maybe we can reference your effort and focus on MQTT jobs . Thanks for your contribution and we will align your effort to Make further implementation. Thanks
The mt7688 has a hardware SPI problem so it does not support full duplex. If you have patches for the latest driver for this processor, id be extremely grateful for a pull request.
Using the patches you provided and by reducing the SPI speed I’ve got MP forwarder running on openWRT. I just need to find some time to create a decent openWRT build job in stead of the hack I used to compile the code.
(I’ve got too much to do and too little time)
I have patches for my fork of lora lib to get it working. Can make them available if you want to use them. I still need to integrate them in my github code base.
That would be great 
Yes, very interesting for SPI and 7688. Because need fix in kernel driver.
or run it in half-duplex.
May be give me link to github for this variant. I can’t found a way. Easy use RPi/NanoPi. If guru provide spi driver for 7688 - possible to use. But now only academic interest. Last discussion on MTK deal with hardware error in SPI interface.
HI，ALl, we are happy to say RAK831+Rasp Pi using the latest SX1301 driver v5.0.1 is done!
We’ve released the software for RAK831+Rasp Pi using the latest SX1301 driver v5.0.1.
You can find it on Github: https://github.com/RAKWireless/RAK831-LoRaGateway-RPi
