[quote user="nattayb"]Would I have better luck writing my own application with pc-ble-driver C code or python? [/quote]

I would have started with a sniffer trace to see if there is any on-going procedure that is not handled:

Though, if you in any case plan to use the pc_ble_driver in an end product I guess you may just as well start try it. Are you sure you are not planning to use the native Bluetooth in Windows? https://www.microsoft.com/en-us/p/bluetooth-le-explorer/9n0ztkf1qd98

Kenneth,

I believe it is a bug with it being overflowed. Also, the snippet is running form the main context.

Hi,

It may be a bug in the nrf connect for desktop (e.g. you are overflowing the serial port, driver or similar), the software+driver+dongle in question is intended for debugging and prototype development, but not for an end product. You can try to add a small delay between transmissions to see if that workaround the problem.

Btw: Make sure that the snippet you have shared is running from main() and not an interrupt context, this make sure that you can still handle BLE events while waiting for data to be sent.

Best regards,
Kenneth
