I need to send data between win 10 desktop and your dongle connected to a microcontroller. So far about nothing is working, so I need some technical support!
You provided some API at http://wiki.seeedstudio.com/Grove-BLE-dual_model-v1.0/#tech-support so one can setup the dongle.
But some commands are not working, or I enter them in incorrect way. Here is an example when dongle is just connected, so no previous commands.
In order to use it from windows side, I have to use Bluetooth LE Advertisements. https://docs.microsoft.com/en-us/windows/uwp/devices-sensors/ble-beacon
How to setup them in your dongle? Does it support it? Is it automated?
