RisingHF RHF0301
Raspberry Pi Adapter v1.0

The gateway device is part number "RHF0M301". It might also be helpful to include reference to PN "RHF4T002" which is the PN for the original PiHat board from RHF.

Reading the datasheet for the NEO-7M (cheap and commonly available chip which fits the PCB's footprint) I notice that pin V_BCKP allows connection of a 3V coin cell for backup of working RAM. This allows for a warm or hot start upon power reconnection which can be handy in some use cases. Currently V_BCKP is tied to VCC, so this should be a matter of picking a common coin cell holder footprint, VC_BCKP from VCC to battery +, and connecting a common ground.

I am trying to get my new concentrator to work with the shield, but it just doesn't want to start the concentrator. I run:

sudo ./packet-forwarder start --reset-pin 7

// Gives
ERROR The program ended following a failure    error=Failed to start concentrator

But it doesn't wanna work. Tried all sorts of pins, but to no avail. Got any ideas? I have ran this before with the same board (this is the second one I bought) and that is working fine, do I have a hardware failure?

PS. I've powered it via USB, and PoE, but don't work, so it doesn't look to be a power issue.
