How can I customize my dev path to reset GPIO values in the configuration file? Instead of using the default.

For the expansion board connecting Raspberry Pi CM4, we create our own expansion board to supplement our products. Not using expansion boards from mature and well-known brands in the market.

In that case, you might want to make some modifications as the Concentratord keeps track of each Vendor / model profile. Please note that different gateway models might have different calibration values. These calibration tables make sure that when the gateway is requested to transmit with tx power X, that tx power X is feed into the antenna. Example:
If you decide to use an existing model, then you can override the reset pins using the following options:
E.g. under the [gateway] section in the TOML config, you can add:
[gateway]
sx1302_reset_chip="/dev/gpiochip0"
sx1302_reset_pin=17
sx1302_power_en_chip="/dev/gpiochip0"
sx1302_power_en_pin=18
Dear author, hello. I am using Raspberry Pi 4 product. I want to implement the lorawan function. Currently, it is running using lora_pkt_fwd I have noticed your subroutine, but I have identified a small issue It defaults to using the spi dev address of/dev/spidev0.0, and the reset address is 7 But my/dev/spidev0.0 and gpio 7 have already been occupied. How can it be customized and changed in the toml configuration file?
error log info
Perhaps there may be configuration fields present
