Hello,

The IoT Toolbox mobile application features NXP’s proprietary tools/applications, including:

NXP BLE Beacon.
Wireless UART.
Over-The-Air Programming (OTAP)

Maybe the guide for the tool might be helpful for you. As those are proprietary, that might be the reason why you can't use other terminals to get the same functionality. Also, consider that the device it's a Bluetooth Low Energy and other applications might be for Bluetooth Classic.

Hello,

I believe you might have a confusion regarding the different Bluetooth profiles, could you please check the following documents available in the SDK of the part?

BLE Application Developer's Guide

BLE Demo Applications User's Guide

Hello,

The Wireless UART application implements both the GATT client and server for the custom Wireless UART profile and
services.

The APP needs to implement service_wireless_uart otherwise the device will BleServDisc_FindService fails and disconnect.
