BLE UART/SPI

[agus.uy]

Hello all,

I'm working on updating bluetooth communication. Currently using a module that receives AT style commands.

The first step will be replacing with nordic device, then change HW and include the code into the SoC.

I have a nRF52 DK, but all the examples are meant to program directly on the nRF52.

Does anyone know if there is a FW I can use that will allow using the nRF52 as a similar module through SPI or UART? Or is the nRF52 a bad choice here?

Thanks for any help you can provide

You mean, you want the nRF52 to act like a BLE "modem" - controlled by AT commands?

[agus.uy]

Basically, yes. Not necessarily AT commands, but yes.

After having a working hardware I'll start moving code to the nRF52

[agus.uy]

OK,

I'm starting from the UART, I'll just change how to connect (security, power)

Is there a way to have some control of the BLE from the application MCU? Because if I understand correctly I have only the UART that goes through.

[awneil]

Yes - you write yourself some sort of UART-based API.

AT Commands is a common example (as initially mentioned) - but you can make up your own protocol to suit your specific needs ... 

EDIT

See: https://devzone.nordicsemi.com/f/nordic-q-a/39029/ble-uart-spi/151049#151049

(the way this forum shuffles posts makes it hard to find specific replies - took me a while to find that!)

I get the idea, to add a layer between the MCU and nRF exposing what I need. I'll work on it.

The SoftDevice is the BLE Stack - the code you write can do the comms with the rest of your system.

thank you!!

I'll probably be back asking about bonding and security, and certification, but on a new post.
