Dont know if it will help but whilst struggling to get quick fix and consistent/stable location lock on RAK5205 trackers (same/similar GPS chip?) over last few days @paulb called out fact I was inside near window (with low K glass treatments etc.) that might be screwing with timing/multipaths etc. When I took outside all fast and stable…perhaps try same with your GW or at least if GPS on long lead get ant outside window whilst testing?! Good Luck!..
Have you open the i2c interface according to the Github readme:
If you have done that, i think that you can reduce the rate of i2c and try again.
You can do as the following steps:
step 1. Check the GPS connection as follow:
step 2: Modify the /boot/config.txt file as the following content to reduce the i2c rate:
Then, restart the GW and check the GPS data.
I’ve just updated the Github repo to add a folder for testing GPS fuction.
You can check it.
maybe its a good idea to contact the developpers (fomi) direct (PM), you could have a broken board, seems you did everything to fix this.
my 2 cents
we should have some update soon. I will keep to update here
I would like to exchange the hardware in your hand. pls email email@example.com
Yes, all of new orders will be shipped the UART GPS version RAK2245 surely now.
In fact, we are contacting the old order customers to exchange the UART GPS version RAK2245 for them. From now on, there is only the UART GPS version RAK2245, no I2C GPS version RAK2245!
Please check the following list about UART GPS and I2C GPS:

As you see, why we use I2C GPS for RAK7243 with LTE? Because RPi has only one UART, and it must be used for RAK2013.
About the software for them:
- If you only want to use LoRa gateway, please download the gateway image directly from RAK website:
My team have prepared two version softwares for every LoRa gateway, including RAK831 + RPi, RAK2245 Pi Hat, RAK7243 without LTE, RAK7243 with LTE. Every device has two softwares, one is based on Raspbian OS, and the other is based on LoRa Gateway OS (Yocto). You can choose one of them to use directly.
- If you want to play the LoRa gateway, and want the source code of them, just find all the source code of them in RAK’s Github repositories:
- This one is used for RAK831, RAK2245 Pi Hat, and RAK7243 without LTE, and it is based on Raspbian OS:
- This one is used for RAK831, RAK2245 Pi Hat, and RAK7243 without LTE, and it is based on LoRa Gatewat OS:
- This one is used for RAK7243 with LTE, and it is based on Raspbian OS:
- This one is used for RAK7243 with LTE, and it is based on LoRa Gateway OS:
My team have worked very hard to release them during the past two month, and just release the last one of them today.
Just enjoy them.
#DIY outdoor gateway using RAK2245 inside
If the Pi is mounted like on the pictures any communication with a backend is appears impossible (with Pi3, not with Pi2).
I was probably still half sleeping…
UTP and USB ports blocked, but of course…
Pi3 have on-board Wifi.
And when ordered from RAK the Pi will be a Pi3B+.
This is an example of a DIY project build with a RAK2245 concentrator.
in RAK’s own (new) online shop they don’t offer this product incl. RPI
To be more precise:
‘And when ordering a RAK2245 kit from RAK with a Pi included, the Pi will be a Pi3B+’.
And yes the enclosure on above DIY project pictures is not from RAK.
I like to know, if the pi hat board will work with Raspberry pi zero w as weil?
The Zero usage would make rak2245 even more affordable.
Yes, it does, I have one running. Hardware - the 40 pin GPIO pin out is the same for all Pi’s and the code works as well.
CPU load hardly goes above 5%, so no need for the extra computing power of a Pi3.
cool, very good to know
which rak2245 you associated your pi zero with?
Pi-Hat, Stamp or 96boards ?
I start loving it as its even run with lora gateway os
