Hello,
I have recently acquired an iC880A-SPI concentrator and a Raspberry Pi 2 Type B to build a gateway using the reference code from Github ( https://github.com/Lora-net/lora_gateway and https://github.com/Lora-net/packet_forwarder )
I have checked IMST documentations here:
http://www.wireless-solutions.de/images/stories/downloads/Radio%20Modules/iC880A/iC880A_Datasheet_V0_15.pdf
http://www.wireless-solutions.de/images/stories/downloads/Radio%20Modules/iC880A/iC880A-SPI_QuickStartGuide.pdf
On paragraphs 1.4 and later from the QuickStartGuide, there are some descriptions of the Pin headers.
I am not very familiar with the GPIO connections on Raspberry Pi and would like to check the wiring between the Pi and the concentrator.
Would I just need to wire CLK/MISO/MOSI/NSS and Reset pins from the IC880A-SPI to the Raspberry Pi 2 ?
What are the corresponding pins on the Raspberry Pi 2 side ?
About power supply on the IC880A-SPI, I suppose it is preferable to provide a separate power supply to the concentrator rather than getting power from the RPI 2 ?
Finally, can anyone confirm having a working gateway with setup similar to mine (RPI2 with iC880A-SPI) ?
Thanks for your help.
