Serial communication (USB) with BLE HID

[ny_quist]

Hello together,

I want to create a program for the nRF52840 DK and later port it to the nRF52840 Dongle (both from Nordic).

The program should

1) over Serial (USB, that is important because of the Dongles native USB port), receive two values (e.g., [50, 20]) and then

2) over BLE, move the mouse on the connected PC/Laptop by those two values (i.e., x->50 pixels; y->20 pixels)

for this

3) it needs to establish a valid connection as BLE HID Mouse first including advertising etc.

My questions are:

a) Are there already similar projects within the nRF5 SDK that I can use?

b) Is this project possible at all?

c) Can someone point me to a good starting point as I'm currently struggling to find information about how to accomplish this. 

I already familiarized myself with programming the nRF52840 DK and Dongle with example applications from the nRF5 SDK.

EDIT://

I started by merging two projects of the SDK together, struggling with compiler errors. Its described here:

Thank you,

Hi ny_quist

What you describe is definitely doable, and combining the two examples you mentioned in the other thread seems like a good place to start. 

It seems you are already in discussions with Karl about the build issue, and I will let him handle that. 

Best regards
Torbjørn
