BRIZIO-H10 - LoRa HAT for Fox Board D27

BRIZIO-H10 is an Fox D27 HAT designed to create personal LoRa gateway or data collector matched to work with the energy harvesting nodes Berta H10.

The Brizio-H10 board houses a H-10 Module that can receive, via LoRa, data sent by on-field H10 sensors, filters it using the on-board firmware and transmits JSON strings to the FOX Board D27 via one of its serial ports.

Programming the Brizio-H10 Firmware

The Brizio-H10 board is provided already programmed but it can be re-programmed directly by the FOX D27 using openocd utility.

On this page:

it is possible to download a microSD Buildroot Linux image ready-to-use with all you need to create your local data colector for H10 nodes.

Go to the directory /root and type:

openocd -f openocd.cfg -c "program packet-forwarder-brizioh10.bin verify" -c "reset run" -c "exit"
