Central Gateway needed? - Kai-Roger - 29.04.2019
Hi.
I was reading this:
http://openrb.com/wp-content/uploads/2019/02/EMBS-LoRa-433-benefits_security.pdf
"Radio messages are time-stamped to prevent replay attacks. Each device
compares time-stamp from received messages with internal clock. If time
difference is larger than accepted range the message is ignored. Central
gateway device provides synchronization timing beacons"
It says that messages is time stamped, and time syncronisation is provided by a central gateway.
If i disconnect the LM from the starter kit, the devices communicates directly to each other.
Does that mean that eventually the messages between the devices will be ignored when the internal clocks of the devices gets unsynced?

Time-stamping is not yet implemented in the current version. When implemented it will be possible to disable it so central device won't be needed.

Good to hear that there will be possibilities to deactivate it :)
