Problem in write characteristic of p2p_client_app.c STM32WB55

Hello! I can not send more that 3 bytes from client to server using the write characteristic(aci_gatt_write_without_resp) in BLE_p2p_client_app.c . When I change CharValueLetgh to something higher then 3 my board cannot notify anymore. How can I solve this issue?

I was able to send more than 3 bytes from client to server. I set aci_gatt_exchange_config(BleApplicationContext.BleApplicationContext_legacy.connectionHandle); in both sides after the connection complete event and set the same CharValueLentgh in both write char's and I was able to send up to 100 bytes!
