As you know, there is a firewall named Great Fire Wall in china, and we can not directly access google, amazon, facebook, twitter, youtube, and so on. We need a VPN to access them.
WisAP is a platform which can build three products: WisLoRa, WisCore, and WisAP. WisCore is a voice gateway which is based on Amazon Alexa voice service, so it need to access Amazon, but in china people can't do it unless they have a VPN. Because that, we integrate a vpn service unabto_tunnel to the platform, WisAP.
I had some other problems with mine. Kept dropping out of RX mode. I found that the power supply that came with it was a bit suspect regarding supplying 2A. I have added a capacitor across the 12v input and another one across the 5V going to the gateway pcb. This seems to have fixed it.
SNR is limited to 10dB, so it didn't really gives the info on the noise level,
I am looking for the noise RSSI, (the sx1276 has registers that allow to read the message RSSI, message SNR and noise RSSI - so I am looking for the same in the RAK 831)
Yes, resetting the 831 should do the trick. I found out that in start.sh which is called during system startup (systemd ttn-gateway.service) this is actually done before starting to talk to the device. The problem was that this script uses RPI GPIO pin 22 but the converter board which is part of the starter kit uses pin 17.
Unfortunately I could not find any documentation for the converter board and I saw the information concerning pin 17 as a side remark in one of the tutorials.
Once changing the pin configuration now the board heats again and it connects to ttn after each reboot as expected. Communication with the WisNode also works fine.
Thanks for your help
Can you remove/ cut one side of strip? Why we don’t remove because heat sink is same dimension of entire converter board but can’t fit inside enclosure! If you buy enclosure, you just need remove one side strip and don’t put heat sink on top! We have another thermal filter for you.!
In addition, to help you cut the one side strip, Pls use tweezers and cutter to remove one side strip,passed cutter over border to make it easier to snap, and snapped it with tweezers. the tools we recommend to use below one
