Can't Connect Blue Tooth
#1
Hi,

Newcomer to this forum,
I have bought some time ago a TouchDRO adaptor for glass and magnetic scales that I received a few weeks ago.
Now, it's time to use it for my refurbished precision old mill. (Stanko 6T75 from former USSR)

Mounting in a small plastic enclosure worked like a breeze together with a miniature 12VDC power supply.
Firing up ended up with a steady green LED and the Bluetooth blue LED flashing 2 times/second...  Right !
But ... no way to get any detection by any of the following various Bluetooth devices :

- Google Nexus 7 / android 5.1.1 (supposed to work together with TouchDRO)
tried also with following to see if there is better success with detection:

- iphone 8
- iphone 5
- DELL Laptop inspiron running win10 with bluetooth module

Tried several times with power off/on in between.

...
In case the power supply may generate interferences, I have also powered it through a 9v battery with no success either with the Bluetooth.
In all cases None of the above listed devices could even see the TouchDRO module   Sad
But they all see each other...

Should I suspect a failure of the Bluetooth module ?

In another message from Yuriy, someone was asking for the possibility to  connect the TouchDRO via USB.
The TX/RX/GND signals are available on the connectors but how to connect to the 4 lines of a standard USB cable ?
Should add some other circuitry ?
Could we get a connection schematics ?

Any idea ?
Thanks
Philippe
