B4R Question esp32 bluetooth host

[peacemaker]

Hi, All

Are we able to make a BT host receiver from ESP32 connected to a USB of PC ?
Just BT to COM-port bridge, to receive any serialized data from other ESP32-BT-device sources.

Initialize an asyncstream in the stream of the serial object and write to it. For the reverse way see in my signature the rDebug.b4xlib in my contributions.

Sub Process_Globals
    Public Serial1 As Serial
    Private astream As AsyncStreams
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    astream.Initialize(Serial1.Stream, "astream_NewData", "astream_Error")
    Log("AppStart")
    astream.Write("I am a stream".GetBytes)
End Sub

Private Sub astream_NewData (Buffer() As Byte)
   
End Sub

Private Sub astream_Error
   
End Sub

Thanks, but how to get BT data first from BT interface?

I do not know. I've never tried it. Although I have an ESP32CAM I just used it a few times and have put it aside never going deeper with it... What about Google?

Searching I found this... Exactly what you need.
