B4J Question [SOlved] Brainboxes BL-819 RS232 to Bluetooth

[Mark Read]

Continuing the thread I started here : https://www.b4x.com/android/forum/threads/brainboxes-bl-819-rs232-to-bluetooth.62572/

I have tried in B4A to get this working but my Tablet (Galaxy Tab 2) has great problems pairing, so I have gone back to my RPi.

This is what I have so far:

RPi with the B4J program below.
A Brainbox BL-819 directly connected to my sensor (yes its the Windsonic yet again, never did solve the RS232 to USB RPi problem).

A log output without and with the bluecove.debug activated.

What happens. I get the connection and the stream is opened but the astream_newdata is never called.
I thought there might be some other problem so I downloaded the SENA app and tried on my tablet - super, the data is coming every second.

Something I am missing.

Hoping for a simple mistake.

[Erel]

Try to remove the call to bt.Listen after the connection and see whether it changes anything.

 

[Mark Read]

Removed the bt.listen and it works. Many thanks.

A small problem is that the data is split into 10 byte pieces but I have a workaround for that.

Now to try and get the same thing working on my tablet with B4A.
