Using Packet Forwarder Without GPS for Class B Beacons

Gateways
1

Hi everyone,

I’m working on a project where I’d like to use the packet forwarder to create Class B beacons, but I don’t have a GPS module available. Instead, my idea is to use NTP for timing synchronization.

Would it be possible to implement this approach for Class B beacons? Are there any specific configurations or adjustments needed to make it work without GPS?

Thanks in advance for your insights!

I don’t see why it cannot if you can keep the time sufficiently accurate, but you probably need to write your own code because the reference lora_pkt_fwd module is made to work with a GPS.

Please take a look at 13.5 of the 1.0.4 LoRaWAN specs. It probably describes what you need.
