NRF52840 Bluetooth data transfer.

[Eas38]

Dear Sir/Madam,

I have bought NRF52840 dongle to bring up my prototype as fast as possible. I am new to Bluetooth tech.

My application requires following peripheral,

1. Bluetooth for data transfer to either laptop or smartphone.

2. SPI in master configuration.

3. Timer configuration.

After downloading the SDK, there are lots of examples program and I am confused which to use.

From my above requirements, could you tell me which example program  I should follow up and kindly provide any explanation document made for program.

Kindly provide your support.

Hi, 

I have bought NRF52840 dongle to bring up my prototype as fast as possible. I am new to Bluetooth tech.

I would suggest you use nRF52840DK for the development because the nRF52840 dongle doesn't have the on-board debugger. Please also see this tutorial nrf52840-dongle-programming-tutorial for the usage. 

1. Bluetooth for data transfer to either laptop or smartphone.

Not sure what data you want to transfer. You can refer to this post.  

2. SPI in master configuration.

 See SPI Master Example

 

3. Timer configuration.

 See application-timer-tutorial
