Unable to receive notification in a laptop with nRF Connect for Desktop and nRF52840 dongle

Hi,

When I use Texas Instruments CC2650 MODA (using Bluetooth 4.2) as the the transmitter, a smartphone (iPhone or an Android phone) that has nRF Connect app as a receiver can receive streamed data after enabling notification.

However, when using different laptops (MacBook Pro, Windows 7 or Windows 10) with a nRF52840 dongle inserted and have nRF Connect for Desktop installed, I can read and write but cannot stream data after enabling notification.

I wonder if anyone encounters this issue? Is there a solution to receive notification from a laptop with a nRF52840 dongle and nRF Connect for Desktop installed?

Note that the same MacBook Pro with LightBlue software can receive notification from CC2650MODA, with no need of a dongle.

The following table summarizes the results using different receivers 

Type of receiver	nRF Connect
iPhone nRF Connect app	Notification works
Android nRF Connect app	Notification works
MacBook Pro with nRF82840 dongle nRF Connect for Desktop installed	Can write   Can read  Notification does not work
Laptop with Windows 7 with nRF82840 dongle nRF Connect for Desktop installed	Can write   Can read  Notification does not work
Laptop with Windows 10 with nRF82840 dongle nRF Connect for Desktop installed	Can write   Can read  Notification does not work
Raspberry Pi 3B+	Can write   Can read  Notification does not work

Thanks,

Philex

Hi

I'm not able to play the latest video you uploaded. Please upload it in the same format as your first video.

1. Is 28 bytes the full packet, including overhead, etc. as well? I assume the amount of data sent is just above 28 bytes.

2. It should be possible to build the Python version of the pc-ble-driver for ARM architecture, but you have to build this from source.

Best regards,

Simon
