Provisioning through LoRa from Gateway to Device and Vice Versa

Hi. I would like to provision a device (node), SX1272, to a gateway, IC880A, and to the server. The server will then send it back to the gateway and to SX1272 to accept the provision, with the SX1272 seeing the message on the UART. This needs to be documented, with the document done in 2 days and the actual provisioning in 4 days. The budget will be 60 USD. I will send you the relevant files if you are interested. Thank you.
