I am using this LORA gateway, 2287 SPI, RAK Raspberry Pi 4 Kit for LoRaWAN – RAKwireless Store. I am following this tutorial: Quick Start Guide for Raspberry Pi and RAK LPWAN Concentrators | RAKwireless Documentation Center . I am getting an error that is preventing me to connect to the TNN server. Anyone have any suggestions. I used option 7, RAK 7248 no LTE (RAK 2287 SPI+Raspberry Pi), as my RAK version. The error is “Failed to set SX1250_0 in STANDBY_RC mode.” Thank you
The error happened after I switched to the installation of the RAK 2287 USB to RAK 2287 SPI, which fixed the com port issue but not the 1250_0 STANDBY_RC issue. If anyone has any tips or suggestions for fixing the “Failed to set SX1250_0 in STANDBY_RC mode” that would be greatly appreciated.
The way it all works is considerably different - wipe the card and start again with a clean install.
For anyone trying to use a RAK Helium Hotspot V2 (RAK 2287 LoRa concentrator based on Semtech SX1302) as a LoRaWAN-Hotspot for TTN, I would like to share which issues I faced and how it needs to be set up to work.
I installed RAKpi OS, set up portainer at first and then LoRa Basics station for docker (from templates/apllication/lora basics station for docker in left menu) by connecting to web page hosted by your device after setting up portainer at port 9443 (e.g. https://192.168.178.111:9443 or whatever ip your device got).
When setting up LoRa basics station, you need to make sure to have enable GPIO and reset GPIO set up correctly, and you need LNS_KEY (which is TC_KEY) which you get (download) from TTN account when registering a new hotspot in your account. You will download tc.key and cups.key.
you need do open tc.key e.g. using a text editor (e.g textedit on Mac) and copy the key that begins with e.g. NNSXS.ABCDEF…
This key will go into your container configuration for basics station, running in portainer on your RAK hotspot.
Besides that you need to have a EUI that matches the hardware, and this EUI must be put in configuration of the basics station container as well as in TTN when entering the data for the new hotspot registration.
You can get the EUI e.g. by scanning the QRcode on the case of your (former) RAK Helium hotspot on the label just above the USB-C connector.
If you scan the QRcode, you will get something like:
000001122333434,e4:5f:02:68:1d:90,e4:5f:02:68:1d:92
The GatewayEUI that you need to enter in lora basics station configuration and in TTN hotspot registration could e.g. be derived from the e4:5f:02:68:1d:90 Mac address. It should look like e45f02fffe681d90 (note that NOT only ‘:’ are removed).
Despite posts that say otherwise (also ChatGPT is wrong with the pin mapping!), the working and correct GPIOs for RAK Helium Hotspot V2 (with RAK 2287, no LTE) are:
GW_ENABLE_GPIO=16
GW_RESET_GPIO=25
you also set them when configuring lora basics station for docker.
If you need to change settings of that container, you can stop it and press “duplicate/edit”, change the settings and accept by pressing “replace” afterwards.
In the contrary, the settings of the registered hotspot in your TTN account cannot be changed in Avery manner, e.g. if you want to change the EUI there you need to register a new one and delete the old one. Also be aware that registering more than one with the same EUI or name will not work.
Also note, that if you retry with the same name even after deleting the name cannot be used again, in case you are wondering.
Make sure to check the logs of your running lora base station container to troubleshoot if there are any issues in connecting.
In your TTN account when selecting your newly created gateway, you should see some uplinks and maybe downlinks happening as soon as devices use your hotspot.
