No. I urged you to connect PPS as it provides better time stamping of received packets.
Beacons are for Class B devices. As
- TTN currently does not support Class B (or Class C)
- I haven’t found any Class B (or Class C) devices available yet,
I did not invest time yet to refactor the required code out of the Semtech protocol stack. (Class B and C are on the roadmap so I will probably look at it in due time, commercial projects have priority right now, TTN has become a money sink over the last year and half so I would like to have a bit of the ‘LoRaWAN pie’ as well)
If you really want beacons at this moment you will need to connect the packet forwarder to a back-end using the Semtech protocol (the Semtech site is a candidate) and also enable beacons in the configuration.
Keep in mind enabling beacons means the gateway will be sending more often and the current generation of gateways do not listen while transmitting so you are more likely to miss transmissions from nodes.
