Hi Johan,

I increased the stack size to CONFIG_BT_RX_STACK_SIZE=2048 (I don't
understand why the real stack size is reported to be 2348), anyhow it
gives a new hard fault (but now with assert: '0' failed):

Kernel stacks:
main (real size 512): unused 220 usage 292 / 512 (57
%)
idle (real size 256): unused 200 usage 56 / 256 (21 %)
interrupt (real size 2048): unused 1640 usage 408 / 2048 (19
%)
workqueue (real size 2048): unused 1668 usage 380 / 2048 (18
%)
prio recv thread stack (real size 748): unused 440 usage 308 /
748
(41 %)
recv thread stack (real size 2348): unused 308 usage 2040 /
2348 (86 %)
[bt] [ERR] isr_rx_conn_pkt_ctrl: assert: '0' failed
***** HARD FAULT *****
Executing thread ID (thread): 0x200023dc

This is a BLE Controller assert that hit. Can you give us a couple of
additional tidbits of info to help us diagnose?

* What exact Zephyr version are you running? (if master please give us
the commit SHA)
I am using the latest zephyr version (pulled yesterday), commit
d3862d7b39349b079b0d125de0c27e54a41b8aa4
So that's the latest, excludes some fixes that came in some days ago. Thanks.


* What board are you using? Is this a combined (Host + Controller
single-chip) build or are you using 2 chips?

I am using a andtcl board with nrf51822 256kb flash and 32kb ram
Not sure what board that is, can you send a link?


* What configuration are you using? (your .conf file)
Included are the conf file from the mesh source directory, as well as
the .config files from the output directory
Got your config files, so this is a combined build with Host + Controller on a single chip. What would be interesting to know in this case is more info about the peer devices you are interacting with. Can you give us a clue of what dongles/chips/devices are you connecting to, what brand they are and what version? Also the number of simultaneous connections you have at any one time, and the general description of the setup you are running in terms of chips and stacks.

Thanks,

Carles
