Problem with BL651

[GHSN]

Hello,

I'm new to Nordic products.

I have BL651 module and I want to connect it to another CPU over UART. So my question is how can i do it?

I've found in some other questions that this module in a HW only solution so i have to install some firmware. How can I do it?
Does the module contains a bootloader?

How can I make the connection over UART? Do I have to make a protocol UART?

Thank you for your help

In that case, you would make your life a whole lot easier by starting with an nRF52832-DK:

Use that to gain familiarity with the product and the tools before moving on to a 3rd-party module.

This: https://www.lairdconnect.com/wireless-modules/bluetooth-modules/bluetooth-5-modules/bl651-series-bluetooth-module ?

Note that the nRF52810 is a "cut-down" version of the nRF52832 - so requires some "special handling"

So all the more reason to start on the DK!

There are plenty of examples provided in the SDK:

Specifically for the UART:
