Having trouble connecting via Bluetooth?

We know that initial connection issues can be very frustrating. Please keep in mind a couple things when you try to connect. iDVM multimeters connect to your mobile device directly without the need to pair them using your devices “settings” application.

Open the Supco TechLink application, go to the Toolbox, Add New Tools to search for new tools then Tap the meter and the device will try to connect. If this fails, please turn both the meter and the mobile device off. Then turn on the mobile device followed by the meter.

To further troubleshoot this issue, it is possible to use a third party application like PunchThroughs LightBlue application. This application allows you to “sniff” your surrounding area to see what devices are broadcasting their Bluetooth existence. Seeing the iDVM via a third party application would focus attention on our application – this is useful to know. If you don’t see the meter in the third-party application your mobile device may be the culprit. Not all Bluetooth implementation is the same. Although we use the latest Texas Instruments SDK for our Bluetooth module, we can’t be sure it works with every possible manufacturer’s device.

Be sure that your app is up to date

We regularly update our application. Please be sure that you using the current application when working with your meter. Application updates frequently included added features, but sometimes they include critically important bug fixes. You can get the current app on the Apple App Store or Google Play Store by searching any of our supported apps, Supco TechLink, measureQuick HVAC or iDVM2 (iDVM510 only).
