I spent alot of time in the past few weeks trying to connect my DXe to my android phone to the DXe Programing App. I down loaded the Programing app several times after purchasing the spektrum blue tooth module and was unable to connect the two with a consistant connection, it would connect but It would not maintain the connection. I attempted to utilize my wife's I Phone with less than successful results. So I returned the module. I had no problem with my PC connection, but I could not connect with my android phone which made changing setups in the field for several models impossible. I called tech support for Spektrum and inquired if the PC Programing cable SPMA3065 would work with a USB / OTG adapter, they stated it would not work with the phone app. After searching several forums I found a post that stated if you use the PC programing cable SPMA 3065 with a USB / OTG adapter it would give you a faster connection than the spektrum programing audio cable which is no longer in production. So I ordered a USB / OTG Adapter and connected my android phone to my DXe utizing the PC programing cable SPMA3065 with the USB/OTG adapter and it worked perfectly. So for those members out there that are struggling with trying to get your android phone to work with the DXe programing app for a $5 or $6 dollars purchase of a USB / OTG adapter this might solve your connection problems like it did mine. I hope this helps someone with a DXe and a Android phone DXe Programing app connection.
