Hi everyone,

Does anyone manage to solve this issue ?

I am working with nRF5 SDK for Thread and Zigbee v4.1.0 on Keil, with only nRF52840 FTD devices with BLE/OpenThread running in the same time.
In the channel-manager.h file we can find:
" *   The functions in this module are available when Channel Manager feature
*   (`OPENTHREAD_CONFIG_CHANNEL_MANAGER_ENABLE`) is enabled. Channel Manager is available only on an FTD build.
*"

I have tried to add
    - OPENTHREAD_CONFIG_CHANNEL_MANAGER_ENABLE,
    - OPENTHREAD_CONFIG_CHANNEL_MANAGER_ENABLE=y
    - CONFIG_OPENTHREAD_CHANNEL_MONITOR=y
in the project C/C++ Define options, but it never compiles, I always get the following error message.

.\_build\nrf_app.axf: Error: L6218E: Undefined symbol otChannelManagerSetAutoChannelSelectionEnabled (referred from thread_utils.o).
.\_build\nrf_app.axf: Error: L6218E: Undefined symbol otChannelManagerSetAutoChannelSelectionInterval (referred from thread_utils.o).

Any ideas ?

You can try

CONFIG_OPENTHREAD_CHANNEL_MONITOR=y

Hey,

i ran into the same problem, the undefined reference... The library is not included in the project and is not compiled at all!?

Hopefully there will be an answer this time (Sorry but it is so frustrating running from one quirk/bug into an other and waiting and waiting for answers).

Regards

Sören

Hello,

due to low staffing, you should expect some delay in response time until Tuesday. Thank you for your patience.
