I don't think I am going to get this working. It seems GATT comms is only possible if the device is already paired. And there is no api for paring programmatically. :( Perhaps I can do it on android.

I am searching for all btle devices with BluetoothLEAdvertisementWatcher. It works fine but I need a device handle so I can use GATT api's. How do I get a device handle from the information provided in BluetoothLEAdvertisementReceivedEventArgs?

Hi, I am trying to read program flash on a pic18f67k22. From the datasheet... "The TBLRD instruction is used to retrieve data from program memory and places it into data RAM" example in ASM... TBLRD*+ How do I execute "TBLRD*+" in 'C'? - Thanks

When does windows read its inf (usb driver) files? Does it do it during the boot process? Or as part of device enumeration? Or something else? Thanks.

Thanks Jochen, The USB device in question is implemented by me, so I know that ZLP's are not required and under normal operation all packets will be read imediatly (pretty quick anyway). So I should not need to call WinUsb_FlushPipe. Thanks again.

How does one contact admin on CP? Thanks.

Do I need to call WinUsb_FlushPipe after every write, if I need to be sure all the data is sent immediately? Or is it only needed under certain conditions? Thanks.

Thanks for the replies. I will give it a try later today.

Hi, I need to convert 4 bytes in to a float or double in C#. The 4 bytes come from the comm port and are read in to a byte array, how can I convert back to a float?

I have a usb hid device under development. When I send a report with WriteFile() (Win32) only every other report is received. WriteFile returns report len + 1 in the lpNumberOfBytesWritten parameter, which is correct (+1 for the report id, which I set to zero). I am 99% sure its not a device issue. Any ideas why only every other report gets through?
