How do I rectify this type of error? Iam using a RAK7391 Gateway with RAK5146 concentrator module?

I scanned my concentrator found that it is in “/dev/ttyACM1” but while installing I choose RAK5146(SPI) instead of RAK5146(USB) from the gateway model selection list, can anyone tell me how to rectify this?
I ran ./choose_model.sh and tried changing it to RAK5146(USB) but again when I run ./start.sh I find some issues in the reset gpio and failed to start the concentrator !

Hi DIvya

What kind of issues? When using the USB version the GPIO reset is not required (although rak_common_for_gateway does it anyway).
BTW, I strongly recommend to use RAKPiOS and rakpios-cli instead of rak_common_for _gateway since we are slowly removing support for the later.

Hi Xose,

Reset issues:
“./start.sh: line 7: /sys/class/gpio/gpio17/direction: Permission denied” I can see that the gpio17 not created inside sys/class/gpio also tried using gpio 22 facing the same issue
As per your recommendation how should I go back to RAKPIOS as my username changed from RAKPIOS to ttn-gateway? (how to uninstall rak_common_for _gateway)

Thankyou.

Hi Xose,

This question might be silly but I just wanted to know, by ordering a gateway from RAK Wireless RAK7391 LoRa gateway with RAK5146 ( SX1303 LoRa Core in slot 2) and RAK5148 (2.4 GHz mini PCIe Concentrator in slot 1) just by powering it will it get connected to the Network server? I understand that initial configurations must be done like selecting frequency band, location, network server, fetching EUI etc ?

Thankyou.

xoseperez · July 26, 2023, 12:14pm

rak_common_for_gateway does not change the username, only the hostname. That’s not a big issue. You can stop and disable the ttn-gateway service and you are good. Of course a more clean option would be to flash RAKPiOS anew. But up to you.

The RAK7391 comes in two flavours: with RAKPiOS flashed or not. Either way you have to go through the configuration process using rakpios-cli. Check here: RAKPiOS | RAKwireless Documentation Center

Hi Xose,

Tried to configure using the rakpios-cli command,
Service - UDP Packet forwarder
TTN region - au1
Freq plan - in 865-867
interface, model - USB, RAK5146
Reset - 17
power pin - 0
port - 1700 etc
also I am not able to see the logs !
the gateway is disconnected in the TTN console, how to rectify ?

xoseperez · July 27, 2023, 6:33am

There is an option from within rakpios-cli to see the logs, and, since what it does is run a docker container in the background, you can also check the logs using docker:

docker logs -f udp-packet-forwarder

(please mind I wrote this out of memory, the name of the container might be slightly different).

Hi,
Getting this error - “Gateway EUI: cat app local conf json no such file or directory” while configuring through “rakpios-cli” command
Thankyou.

DivyaM · July 29, 2023, 3:01pm

Hi Xose,

Can you help me rectify the above error?

xoseperez · August 1, 2023, 9:22am

Hi Divya
That’s a weird error, looks like the service was not running when you queried for the service information. Will try to reproduce it on my side.

DivyaM · August 1, 2023, 9:46am

Is it safe to flash the rakpios into the SD card, boot the compute module 4 using SD card and try configuring it as a LoRa gateway using rakpios-cli command as per your recommendation ?

xoseperez · August 1, 2023, 10:02am

Well, that’s what it’s meant for
Mind that booting the CM4 using an SD card will only work with Lite versions of the CM4 (without eMMC). If your CM4 has eMMC you will have to flash the RAKPiOS on the eMMC, the SD card won’t work (this is a limitation/feature of the CM4, nothing to do with the WisGate Connect).
