Basic Assembly and Setup

I cannot get the mobile app to recognize Bittle via Bluetooth.

I used the Desktop app (Windows) to upload the firmware and to calibrate.

Bittle works fine with the IR keypad but not on Bluetooth.

To run the app on my phone.

I turn on Bluetooth and location.

Then open the Petoi App.

Petoi app scans but does not find Bittle.

App re-scans and still does not find Bittle.

Led light on Bluetooth card continues to blink.

However, I can go to the Bluetooth app on my phone and pair Bittle.

Bittle is recognized. Led light is steady.

Bittle wakes ups, beeps, moves a little.

then after a few seconds Bluetooth connection is dropped.

Led light goes back to blinking and Bittle is unpaired.

No Bluetooth connection to Bittle.

What am I doing wrong??

PS at this moment I have no arduino ide, python etc. programing experience and purchased Bittle to learn. thx
