Connect nRF52832 with PC

[Ashiq Mohammed]

I want to connect nRF52832 with PC. The objective is using nRF52832(I am using BT832 Module) I have to scan all Blue Tooth deceives details and send to PC. Please help with pin connection with sample code.

What do you mean, "connect" ?

• a wireless connection,  over BLE ?
• USB ?
• UART?
• or what?

You mean one of these: https://www.fanstel.com/bt832-1-1/  ?

That's what the Dev Kit is for!

You could either use Fanstel's own "Evaluation Board EV BT832" - listed on that page - or a Nordic nRF52-DK

Yes awneil, I am using BT832F ( https://www.fanstel.com/bt832-1-1)

I have nRF52 DK and able to program BT832F.  

I am expecting diagram of Wired connection between BT832F and Desktop USB for sending data from BT832F to USB. Please help.

Hello,

The nRF52832 does not have a USB peripheral. The reason it works with the nRF52832 DK is that it uses UART to communicate with the SEGGER chip on board the DK, which translates data to USB.

If you want a device that works as a USB device, you must use the nRF52840.

Best regards,

Or use a USB-to-UART chip, or a USB-to-UART cable; eg,

EDIT

The Fanstel Evaluation Board uses a USB-to-UART chip - you can download the schematic from the link given in my previous reply.

Thanks Edvin. I have decided to go for nRF52840. How I can send the text data to USB of nRF52840?

Hello,

That depends on your computer application, and how you want your data. 

It is true as awneil says, that you can use a UART to USB cable, which will do the job that the programming chip usually does on the DK (UART job, can't be used for programming).

I really recommend you to start with an nRF52840 DK, as it is a lot (!) easier to develop on than e.g. the dongle. First when you have something up and running, you can switch to the dongle.

As I mentioned, it depends on how your computer application wants the data. I suggest that you start by looking at some of the USB examples from SDK 15.2.0, such as this one.

Best regards,

Edvin

Absolutely!
