6LoWPAN over BLE: Device not pingable

[Citrullin]

Description

I am not able to ping my device with 6LoWPAN on BLE from my linux machine.
Possible issue: As @miri64 mentioned in an issue, the header compression might be the issue. So, I added USEMODULE += gnrc_sixlowpan_iphc to my Makefile.

Steps to reproduce the issue

1. Since gnrc networking with BLE does not work at the moment. You need to checkout the commit 60008cb.
2. Flash the gnrc_networking example
3. Follow the 6LoWPAN BLE guide
4. The ping ping6 [DEVICE_LOCAL_ADDRESS]%bt0 responds with address unreachable.
   In my case:
   From fe80::1a:7dff:feda:7113%bt0 icmp_seq=1 Destination unreachable: Address unreachable

Expected results

Device to be pinagble.

Actual results

The device doesn't respond on pings.

Can you also post the OS version you are using? Given that the Nordic Softdevice only works with certain kernel versions this is kind of important.

As you are using gnrc_networking (which includes gnrc_sixlowpan_iphc) and the referenced issue is about gnrc_minimal (which does not include it), I highly doubt that.

"but newer kernel versions than 4.12 definitely don't work"
Shit... Thanks.

[miri64]

@haukepetersen is currently working on a GNRC-integration for nimBLE which should be ready soon™, so the boards currently using the softdevices could hopefully use nimBLE in the future instead. Alternatively, (if possible) the softdevice needs to be ported to a newer version.

[Citrullin]

@miri64 I would be really happy with nimBLE. I always prefer the open source solution. So does that mean @haukepetersen is implementing the IPSP characteristics for Bluetooth in nimBLE?

@miri64
Kernel version 4.12 does not work.

4.12.14-041214-generic

But 4.10 works fine. :)

Yes, thats exactly what I am doing right now. PR should be coming up 2nd week of April (I am on holiday next week...).

As #10816 was merged now, I think we can close this.
