NRF5340 connection to PC through BLE or other

[zhaoyuan]

Hello,

I have a nrf5340 and pc based on Windows OS. I want to transmit information from 5340 to pc at a speed of 300kbps. Here are my two plans:

1. Using BLE protocol. I have try some examples such as pybleak. However, pybleak can't build a stable connection under the speed of 300kbps. Is there any api or program produced by nordic can be used or referred?
2. Using ble-to-usb. I have little experience on this. Is there any nordic products or 5340 can play this role?

Thanks for your help.

Hi Zhaoyuan, 

Our solution on PC requires a dongle to be connected to the PC. So it's more like option 2 you have. 
You can use nRF52840 dongle or any nRF52 DK as the backend for the PC. Then you can use the nRF Connect Desktop - Bluetooth Low Energy app to interface with the dongle and then connect to the nRF53. 

We don't have much experience with option 1 when you access the native BLE on Windows. Have you tried to use Microsoft example here ?

Hi Hung,

We have tried nRF52840 and achieved connection by nRF Connect Desktop. Besides, we would like build a GUI based on python. Does nRF Connect Desktop have any api can be called to get raw data? Or can you give me some demos where nRF52840 serves as ble-to-usb? Thanks for your advice!

Hi Zhaoyuan, 

It's actually possible to build application based on the nRF Connect Desktop platform. You can have a look at this RSSI Viewer example. 

If you want to build your application based on python, there is a python bindings with example here.

Hi Hung,

I will try pc-ble-driver-py. Thanks for your help!
