MTU with BLE-MESH & BLE

[elDi@mond]

Hi, everyone
My project assuming coexist BLE-MESH and BLE in parallel. I need to send some amount of data (about 2-4Kb) thru BLE. So i hit problem unable to change MTU size.
esp_ble_gatt_set_local_mtu(517) returns ESP_OK
When connecting there are message:

Code: Select all

ESP_GATTS_MTU_EVT, MTU 23

Thru NRF-connect i trying to Request MTU and geting message:

Code: Select all

Requested MTU not supported. MTU changed to: 23

Is there any possibilities to increase MTU size?
