That’s pin 12 of the concentrator. Their website seems to suggest they will supply a schematic once you have bought it, if you have a schematic of the backplane, I should be able to work out the raspberry pin pin number. Then assuming that your using jpmeigers resin image, you can set an environement variable for: GW_RESET_PIN to the appropiate pin.
Have you tried with the default? Skimming the instructions I did not see anything about changing the Zurich script which I think is set up for the default. (Default does not require setting it)
I ordered myself one of these LoRaGo PORTs. I can confirm that the default reset pin (22) is the correct one for this board. I however do get that it takes a few tries before the concentrator successfully starts. I also had to bring the SPI speed down a bit using: SPI_SPEED = 1000000
Regarding the LoRaGo PORT kit, I am impressed by how easy it is to plug everything together and on top of a raspberry pi. I was even able to reuse an existing Pi that had a Linklabs shield plugged on top of it.
One issue that I encountered was that the u.FL to SMA cable that I received was not the correct type. I got a u.FL to SMA-R (reverse polarity) cable, and the antenna is SMA. So the antenna can not be connected to the board. The antenna itself is also not that great at 868MHz. So if you are planning to get one of these boards, order your own u.FL cable and a proper antenna.
The number of times I’m getting the “ERROR: [main] failed to start the concentrator” messages are increasing. In the meantime util_spi_stress -t 4 runs without an issue. This is with the Zurich setup according to the official LoRaGo PORT documentation.
I’m confused why the SPI test is fine, but the concentrator does not want to start. I’ve even tried multiple Raspberry Pi 3’s.
