Ble communication between nordic board nrf52dk and windows pc

[antoine98]

Hello, 

I have impelemented a communication ble between two boards nrf52dk. This is correctly working and communication is very fast. 

I want to implement a communication between board and Pc, in which board acts as a peripheral and pc as a central device so that the board sends data and pc receives them.

I have implemented something like that using Matlab ble functions:

Connect to Bluetooth Low Energy peripheral device - MATLAB - MathWorks Italia

However, even if the communication works it is really slow. Probably because I'm not able using Matlab to set the same parameters as in the connection board-board such as connection interval, phy etc.

Is there any other language which allows me to make the communication board-pc? Is anyone else using Matlab like me? If yes, how is it possible to optimize the parameters for the central in Matlab? 

I'm not able to find any application like the one intended from me except the ones which uses serial port.

Hi,

Unfortunately we do not have expertise with Matlab BLE connections.

I think I would recommend that you use a nRF52840Dongle (Or DK) in the PC to do BLE communication, and then communicate over the USB with MatLab.

I will let this ticket be open, in case any members of the community has any experience with this.

Thanks for the answer Sigurd, I was wondering if there is a way to have a direct Ble communication between board and pc avoiding the usage of serial port, but I can’t find anything related.

Is there nothing related even in other languages other than Matlab?

I dug a bit and found that Windows does not support Bluetooth Low Energy, which we use in our nRF chips. Linux, on the other side, has drivers for this.

Thanks Sigurd, can you provide me some information about linux drivers you have found? Just to have a better understanding. Thanks a lot, I appreciate your effort
