Unable to find NUS (Nordic UART BLE Service) specification document.

[SPDemers]

Hi,

For testing purposes, I need a copy of the spec that the Nordic UART BLE service adheres to. Ex. minimum capabilities, mandatory functionality and attributes, etc.

More or less, something I can use to validate that NUS on our device is working as it is expected to work with NUS on other devices. In this case, our device is an nRF52840 using s140.

Official documentation from Nordic is what I am looking for.

Hi, 

Are you using nRF5 SDK? Then, you can refer to the test section in the UART/Serial Port Emulation over BLE, and Nordic UART Service API.

https://learn.adafruit.com/introducing-adafruit-ble-bluetooth-low-energy-friend/uart-service might be helpful. 

Regards,
