New Ti board - no scale

[ThLDQ]

I go on investigating...
I downloaded SerialBluetoothTerminal from Playstore and it shows a Bluetooth activity :

I suppressed many "^@x0;y0;z0;w0;" lines to lighten the post...
So it looks that the Bluetooth board is emitting.
I checked the continuity of my soldering : it's OK.

Did  I say that the scale is a Shahe scale?

How to be sure that the program is well loaded in the 2553 chip ?
I use Windows 10 and I followed the instructions on the "How to upload firmware to MSP430" page of the site with this result :

It looks normal ....
But who knows ?
