FarDriver Bluetooth Adapter / Dongle.

Vendor sell you a controller, but no adapter / dongle to program via Android or iOS? Maybe your adapter isn’t functioning properly? Why wait weeks when you could have one in your hands within days?  These units are fresh from the factory!

The most common Android error is not having the MOST recent app (2.3.0 as of 10/30). The last pic shows the common issue.  The play store has the old version and the newest app is tougher to find on there.  No worries, simply join the FB Group:  "Far Driver Tuning for E Bikes !"  This group has an area labeled as "files" and it has the latest app at your fingertips:

***you may find the latest app (it updates frequently) found on www.far-driver.com (products --> controller software & app).  If you're app is out of date, it will prompt you for a new ble as well--bluetooth module may not be the issue.  Just trying to save you all some money***
