[NTNU] Connecting nRF52 to Raspberry Pi, no stable 6LoWPAN connection

Turns out that our main problem was the code on the nRF52. The example code (Nordic_HRM) made LED1 blink as if it was ready to connect, even though it was not.

When we instead used another example code (for instance ipv6 coap server), we where able to connect by writing echo 1 to 6lowpan_enable as Håkon told us, followed by

echo "connect EC:46:xx:xx:xx:xx 1" > 6lowpan_control

to connect the nRF52.

Did you solve the issue, and can you provide the answers here for others to see?

Hi Sindre,

Since the changes in kernel v4.x, you need to enable the module first by echoing 1 to 6lowpan_enable. I believe you do not get any permission error when echoing to 6lowpan_control, even if the module is not enabled.

We're having a stand at NTNU today (E&T dagene), come by and we can have a look at your setup. I'll be from 12, but it will be filled with other personell from Nordic during the whole day.

Cheers, Håkon
