LoRa WM1302-SPI with Raspberry Pi Hat

Products & Technology LoRa

Hi guys,
I tried to run a LoRa gateway based on WM1302 module plus Raspberry with hat https://www.seeedstudio.com/WM1302-Pi-Hat-p-4897.html,
following https://wiki.seeedstudio.com/WM1302_module/
After 2 days of unsuccessful attempts I come to the decision that something’s wrong with the hardware settings. Investigating the Pi 3B+ 40-pin connector pinout, Pi Hat’s pinouts and WM1302 pinouts I can recommend next settings for pins in file reset_lgw.sh in Point 4 in wiki above:

SX1302_RESET_PIN=17
SX1302_POWER_EN_PIN=8
SX1261_RESET_PIN=5
AD5338R_RESET_PIN=13

Although the last line has no meaning, as PiHat internally has nothing connected to GPIO13.
Then thinks started to happen.
I hope this will oils the wheels in your LoRa Gateway development process.

Thanks for you feedback. We will fix this in our wiki. :+1:

Please correct the wiki page accordingly… I spend a lot of hours using a DVM to figure out the same issue.
Everybody buying this product will blindly follow your wiki guidelines without success…

Thanks

Did you by any chance mean 18? The settings provided here on in the wiki don’t work

Yes, barnesom. It was “8” in 2021, but can not say for today. To be sure, pls. check WM1302 chip’s .pdf for desired pin, then routes trough the slots right to the Raspberry board and then you will be sure. Sorry for delay, I missed for a while.
