NRF maximum gatt mtu size


I have a question about the maximum payload size with nRF52832.
I use the SimpleChat example with Arduino IDE to transmit data between SimpleChat to CentralTest example. I am able to transmit only 17 usable bytes in the GattCharacteristic payload.

I read that the maximum payload with BLE 5.0 reached 247 bytes. It seems the RedBear Nano 2 is using BLE 4.2 payload size.

is it correct? and how to transmit more data in a packet with the RedBear Nano 2?
