You can update the MTU size at any point after a copnnection has been established. A GATT server can request an MTU change of the Client, the same is true for the client to the server.

See GATTC ATT_MTU Exchange and GATTS ATT_MTU Exchange API docs.

I still don't understand how to implement it.

I saw sd_ble_gattc_exchange_mtu_request(uint16_t conn_handle,uint16_t client_rx_mtu ) but that needs to be in the host side, no? at what stage? what do I pass for client_rx_mtu ?

What needs to be implemented at the server side?

Same API for sending the data. You need to verify that you've enabled MTU extension. See the message sequence chart i linked to previously for the API callas that you need to search for in your code.

I'm not sure.

Is it enabked by default in the uart example?

If not, how do I enable it? and do I use the same API function for sendinh the data?

Thanks

Have you enabled MTU extension? See GATTC ATT_MTU Exchange
