Hi,
I am using nrf52832dk board for test nus service with ncs2.9.0, but I am facing some problem with MTU setting.
I found a configuration item "
" that seems to be used to configure the MTU, but when I want to set it to 33 bytes, the compilation fails.
The error reason is as follows:
***************************************************************************************************

docs.zephyrproject.org/.../kconfig.html and/or look up
BT_L2CAP_TX_MTU in the menuconfig/guiconfig interface. The Application Development Primer, Setting
Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful
too.

If I can get any tips, I will be very grateful, thank you!
