I have asked about this before .
But after working more on the project, it seems the solution i found before actually didn't solve the problem.
Hence I am asking again....
On 52832, SDK V14.0.0, SD132-5.0
I tried to set NRF_SDH_BLE_GATT_MAX_MTU_SIZE to 247, as from dev-doc i saw that SD132 supports BLE V4.2 DLE.
However it returns:
