Nimble BLE COC (Connection Oriented Channels)

[dave_see]

Hello,

I'm unable to build a the hello-world (from the examples) app with support for NimBLE COC data transport. Using idf.py menuconfig, I set CONFIG_BT_NIMBLE_L2CAP_COC_MAX_NUM to 1.

When make this change and try to build, I see the following error when building hello-world :

Does anyone know how to successfully build with NimBLE COC support?

Many thanks,
Dave

I am also having the same problem. Is there an update on this issue.

I have a slightly different problem… while everything compiles, it just doesn't do anything. Perhaps you could comment on https://github.com/espressif/esp-idf/issues/9044 to raise more awareness for this issue.
