Issues Configuring WM1302 LoRa Module on Seeed reComputer R1000 with ChirpStack OS

ChirpStack Gateway OS
1

Hello everyone,

I’m trying to set up a Seeed Studio reComputer R1000 with ChirpStack OS using a Seeed WM1302 LoRa module in slot 2 (slot 1 is occupied by a 4G LTE module).

However, I haven’t been able to get it working, and the Gateway ID is stuck with the following message:

Gateway ID: Could not read Gateway ID

After some research, it seems the pins may not be set properly for the R1000. According to Seeed Studio, the SPI version of the WM1302 is fully compatible with the R1000, and the pins to use are as follows (please see the Seeed Wiki here):

SX1302_RESET_PIN=580 # SX1302 reset
SX1302_POWER_EN_PIN=578 # SX1302 power enable
SX1261_RESET_PIN=579 # SX1261 reset (LBT / Spectral Scan)
// AD5338R_RESET_PIN=13 # AD5338R reset (full-duplex CN490 reference design)

From the logs in OpenWRT, the pins seem to be set as follows:

Is there a way to change the pins being used? Additionally, is there anything else I need to adjust to get this working?

Update:
Sorry for the silly post. I jumped on the forum a bit too quickly. After some more research, the R1000 is not in the list of supported shields. I got confused by the WM1302 shield from Seeed that is supported.

I would be more than happy to submit a pull request to add support for the reComputer R1000. Could someone point me in the right direction? From what I have found from previous pull requests, I need to create a new .rs file for the R1000 and modify the .mod files accordingly?

I think the best approach would actually be to create a new GW OS image, specifically configured for the reComputer. An example is the RAK7391 gateway, which is also based on the CM4. See for example:
