how to do BLE device's function test in mass production stage ?

[billcarter]

use NRF52832 do a ble hid keyboard, 

when do the keyboard function test need connect the keyboard to computer or laptop.

only when the connection it's done, then can run some mass production software in computer.

but each connect to computer by manual it's very slowly.  Do we have some fast connect way to connect to computer ?

1, it's possible control the computer can fast find and automatic connect desired ble name's device ? 

2, it's possible can do a usb to ble dongler, the dongler can fast connect to the device, and the keyboard data can transfer by usb to the computer ? 

Thanks.

Hello,

You can use an nRF52-DK where you emulate a central device.

For instance you can either modify the central HIDS example or you can use the BT shell to act as a central device:

Thanks for you answer,  I want use NRF52840 to do this function test dongler.  becasue it's have the USB interface. in the computer side just know it's connect to a USB keyboard.  this donlger only be a ble bridge,  but can automatic connect the BLE keyboard, and convert the BLE keyboard's message to USB.

which exampler code it's better for this application ?   if use  central HIDS example, how to convert the message to USB ?

The two suggestions I made you are interfacing BLE over a serial terminal window (UART). This is by far the easiest to do.

If you want to make a dongle that act as a gateway BLE HIDS->USB HIDS, that is more complicated, realistically it's not possible to make a generic parser of HIDS descriptors in an embedded device, so you will likely end up hardcoding the HIDS descriptors 1:1 and then forward the notifications of BLE to the USB HID descriptors. You will likely need to merge the central_hids example I linked with the following example:
