I am using the CMTMN33 module (nRF52833 based) (click here for datasheet) and Zephyr sdk-zephyr-2.1.99-ncs1.
I have implemented firmware to transmit BLE and when BLE is connected we can write BLE GATT characteristic and save it to NVS - non-volatile storage. I was using BE33 module earlier (nRF52833 based) with same code it was working but for CMTMN33 I am getting below error message.

Also I tried to search causes of above errror from this link I tried to set below in prj.conf file but still error persists.
Please help me.
Thanks in advance.
