Sure, there is already the KiCAD file including everything to play around with on your own; added a picture of the schematic here for a quick glance without downloading.
Hey guys aside from these power-consumption issues, I am now running the Feather as gateway and node.
And I get a strange problem.
The gateway is attached to a raspberry pi via usb (by-id), which runs fhem. And everything works great for about an hour to 1 1/2. Then somehow the gateway stops receiving/communicating. I already tried an active USB-Hub incase the power consumption was too high for too long. But that didn't help. I have to reset the gateway and node to make it work again.
Did anybody else ever experience similar behaviour?
This is great, thanks!
One suggestion: add a switch mode regulator that can handle 12 or 24 volt DC input. This will allow small sensor devices to hang off a typical bus network having extra pairs for the central power supply.
@DeepCore not wrong frequency no. But it looks like the feather doesn’t come with the antenna pre-soldered. Since the devices should be identical otherwise, the antenna could be what differs. But if it was, the rssi would probably have been different as well.
High sensitivity: down to -148 dBm.
From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.
