just in case, note that the examples you gave in the iot-lab wiki were
written for the iot-lab nodes port for Contiki.
So will not directly apply to RIOT for the macro names.
I understand that you can need both limiting power and increasing the
threshold when you want to have a lower connectivity with the hardware
deployment in IoT-LAB.
The "set_rssi_threshold" is currently not implemented in RIOT, but you
could easily do it yourself (and do a PR maybe :))
The code I wrote in openlab was this one
And it could be adapted by using RIOT at86rf2xx API like:
From looking in the other at86rfxx drivers datasheets the configuration
is the same but with different values for RSSI configuration
* at86rf231 page 103
* at86rf212b page 120
* at86rf233 page 113
So the threshold definitions should be enclosed in the header with `#if
