Bluetooth Connection Issue for Code in Makeblock App and mBlock Blockly


Hello, My mBot will connect via bluetooth to my Android smartphone via the Makeblock App and allows me to control the mBot. When I switch from Play to Code the bluetooth symbol in the upper right turns red, and the blue light on the mBot goes back to blinking.

The Code section of the Makeblock app launches the mBlock Blockly app, and my mBot will not connect via bluetooth in mBlock Blockly app.

I have tested with another Android smartphone and it will connect via bluetooth in the mBlock Blockly App just fine.

So, a different device connects just fine and my device will connect via bluetooth to simply control the mBot but when I try to connect in order to write block code in the mBot Blocky App, it will not connect.

What can I try to troubleshoot?
