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
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
