External MCU Interfaced with Nrf52811

[RicFlair]

Hello, i am looking for documentation in regards to interfacing a external mcu with  Nrf52811 via  UART. 

Is there a UART example or AT Client that needs to be flashed to the nrf52 and then i would be able to send AT commands from the external Mcu over the serial port? TX/RX? 

I then would like to connect to a phone and transmit some logged data as well from the Ble link to phone. 

Thanks

Looks like you are looking for a serialization library to use nRF52811 as a connectivity chip with you own dedicated application MCU.

The release notes of SDK 15.0 say that you can use SDK15.0 which implemented serialization codecs for S112v6.0. I am not sure if S112v7.0.1 Serialization codeds are implemented yet.

According to this matrix, you can use S112v6.1.1 on SDK15.3 on nRf52811. 

Since 6.1.1 is only minor version change, the API should be compatible with S112v6.0.0. So using SDK15.3v S112v6.1.1 should be ok to use for your case.

Thanks for the quick response Susheel, As a follow up. If I order a brand new nrf52811, do you know if it will include the SDK or will I need to program it first?

You need to program the examples after downloading the SDK here
