There is a pretty featured library for controlling the WIFI called WIFININA. Oem capture easycap driver for mac. This library does NOT have any bluetooth functions though. Therefore, until someone writes a library which lets you control the bluetooth functions of that ESP32 chip, I don't think you'll be able to send arbitrary serial data via bluetooth. The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10.

To repair statusdevicepowerfailure error, you may need to re-install the Bluetooth/Sound/Intel MEI or any other drivers on your PC. To do it, follow these instructions. At first, Open the Device Manager again like method 3.

This app supports different bluetooth versions: - Bluetooth Classic - Bluetooth LE / Bluetooth Low Energy / BLE / Bluetooth Smart This app supports different bluetooth devices.
Now that the Raspberry Pi 3 comes with Bluetooth and WiFi built-in, people (including me) were excited at the increased flexibility this offers. I was already thinking about using the Pi 3 in my Raspberry PiStation build so that I could do away with the extra dongles. Setting up the WiFi was straight forward – it was the same process when using USB WiFi adapters, but getting the Bluetooth module to work properly was a little more complex and I found it a little frustrating. Hopefully my guide will help you fix Raspberry Pi 3 Bluetooth issues!
Fix Raspberry Pi 3 Bluetooth Issues
There are many guides on how to get Bluetooth working on Raspberry Pi 3 already, but again I found that some crucial steps were missing in order for mine to work properly, so I have combined everything into one post here.
On the latest version of Raspbian Jessie (2016-02-26 at the time of writing), there were some additional modules that needed installing to fix Bluetooth on Raspberry Pi 3. If you are on an earlier version of Jessie, then you will more than likely need to run:

You may then need to update the firmware used in the Bluetooth module, which is done by running the following:
And then to install the user interface, which is very handy if you are running your Raspberry Pi 3 in desktop mode:
Now at this point, many guides I read stated that a quick reboot and then Bluetooth would be working and accessible through Bluetooth Manager in Menu -> Preferences -> Bluetooth Manager, but I found that whilst this was an option, selecting Bluetooth Manager did absolutely nothing.
After an hour or so of frustrated searches online, I stumbled across a page that stated “this happens because when Raspbian installs Blueman and the other Bluetooth software, it does not automatically add ordinary users to the “bluetooth” group. This group gives users permissions to access D-Bus, which Bluetooth uses for communication in Raspbian. This causes a “Permission Denied” error whenever a Bluetooth process initiated by the unprivileged user attempts to access Blueman.”
So to fix Raspberry Pi 3 Bluetooth issues, you need to run the following code in your terminal:
And to check this has worked, type:
If this has worked, you should now see the following:
If you run “cat /etc/group | grep bluetooth” in your terminal, you should see this…
Then after a quick reboot:
You should now be greeted with the Bluetooth Manager icon on your taskbar, which means everything has worked!
Get link. If Bluetooth Manager has loaded, you should now see it on your taskbar!
And there we go – hopefully you can now access Bluetooth Manager and pair with your devices and get cracking!

Try turning off Wireless, We are trying to get the COM ports to work as well.
Try this Microsoft suggestion -
Installing Legacy COM Ports
The Serial function driver always configures a legacy serial port as a COM port.
Serial detects the presence of legacy ports by reading corresponding COM port subkeys under the .ServicesSerialParameters key. To install a legacy COM port, you must set a legacy COM port subkey for the device under this key. The COM port subkey contains the registry settings for a legacy COM port.
Bluetooth Serial Failure Failed To Open An Rfcomm Serial Channel
When Serial is loaded it determines which legacy ports were not previously detected by checking the LegacyDiscovered entry value for a legacy port. If this entry value does not exist or is zero, Serial performs the following tasks:
Bluetooth Serial Connection
- Calls IoReportDetectedDevice to report the device to the Plug and Play manager.
- Sets the LegacyDiscovered entry value for the port to 0x00000001, which indicates that the port has been reported.
- Copies some of the entry values under the COM port subkey to the Plug and Play device key for the physical device object (PDO) that is returned by IoReportDetectedDevice.
- Serial sets the PortName entry value under the Plug and Play device key to the value of the DosDevicesentry value under the legacy COM port subkey. For all other entry values that Serial copies, it retains the same entry value name. For more information about which entry values that Serial copies, see the Serial sample code provided in the Microsoft Windows Driver Kit (WDK).
The IoReportDetectedDevice call marks the port as a root-enumerated device. On subsequent system boots, the Plug and Play manager automatically configures the device based on the information in its INF file.
Bluetooth Serial App
The Plug and Play manager creates the following compatible IDs for a legacy COM port: DETECTEDInternalSerial and DETECTEDSerial.
