1 year ago Thanks @frieger :+1: I'm going to rename this entry from:
emb_raspi_130x_cape_lr1302 -> embit_emb_lr1302_mpcie to be consistent with the other entries. The Cape is only significant for connecting with the Raspberry Pi GPIO pins, it doesn't change the implemented frequencies, gain table entries etc... I will keep the pins as defined in your config and thus the default will map to the Cape pins, but users are free to re-configure these to other values (when the module is used in other gateways without the Cape).
Tested and working on a Raspberry Pi Zero with Chirpstack Gateway OS.
The Embit hardware can supposedly be found in some commercial gateways, such as the Controllino Hotspot and (probably) the Arduino Pro Gateway, which are now readily available on the used market and thus worthwile to support.
The Raspbery Pi HAT (or "Cape", as Embit calls it): http://www.embit.eu/products/oem-gateways/accessories/emb-raspi-lr130x-cape/ The concentrator card: http://www.embit.eu/products/oem-gateways/emb-lr1302-mpci-e-prova/
The concentrator card uses an SX1250, nothing special. Initial configuration copied from the Waveshare card, as they are nearly identical apart from the pins used for reset and enable and the address of the temperature sensor.
