Using the nrf52840dongle as Border Router
For using the nrf52840dongle as a 6LoWPAN border router with the Raspberry Pi it is recommended to use the example application from the corresponding AllRIOT GitHub repository.
Alternatively you can also use the gnrc_border_router
example from the default RIOT repository and replace ethos
by cdc-ecm
in the UPLINK
variable of the Makefile
.
