USB Android Serial

Bump…

Trying with no luck to implement the direct “Photon to Android” OTG serial connection as outlined here in the @rickkas7 tutorial: Serial Tutorial

I’ve tried multiple Android devices (S3 running v4.1.2 / S5 running 6.0.1) and I’ve tried all variants of potential USB configuration in my Android 6 device (charging, MTP, PTP, etc…).

I’ve also verified the cables are operational (connecting to other devices), and I’ve downloaded the cited Play Store app (and others) to no avail.

Does anyone have an operational tandem of Photon and Android software, and if so could you please share the particulars? Having a small serial debug terminal on a Smart Phone would be a great tool for my applications.

Thanks in advance.
