nRF52840-DK and RAK811 WisNode (v1.2)

Anybody managed to connect a WisNode RAK811 to an nRF52840-DK and make them “talk” ? (send “at” commands to the RAK811 shield and get replies)

How did you connect it ?
using wires ?
simply attached it on top of the nRF52840-DK ?
what jumper configuration on the RAK811 ?

Hi @Oberon. Connecting with wires or using it like hat, depends on the version of WisNode. You can see the basic connection pinout here: . Basically you need tx, rx, vcc and gnd.
For AT commands you can see this Arduino sample code :
