Hello Zephyr Community,
I found where something is wrong.
Indeed in net_context_get function, I saw that I reached
CONFIG_NET_MAX_CONTEXTS (equal to 10 in my prj.conf).
For your information, I use UBLOX sara r4 driver (on zephyr
1.14.1 as I mentionned in my previous mail) and I wonder if
contexts are well managed in this revision, especially when
socket is closed ?
There could certainly be a bug in the socket offloading layer for
UBLOX Sara R4 (I'm the maintainer for the current modem layer in
Can you open an issue here:
Please include as much information as you can (from this email
- Zephyr version: 1.14.1
- Sample used: samples/net/mqtt_publisher
- Firmware version on SARA R4 modem
And add me as "Assignee"
Thanks in advance for your help
And just to add some
precision, I work on zephyr 1.14.1.
