What make/model of phone?
oh well, over the years i've accumulated a few :lol:
including a sam s4, sam s7 and more recently an asus zenfone 3, my sam s7 died just shortly after warranty expires, luckily they didn't go up in flames just like those sam note 7 :P later i bought an asus zenfone 3 deluxe instead as a replacement

@roger
yup LineageOS as i've heard is a good development though i've yet to try it out, it's a great thing that volunteers have put together what is remnants of CyanogenMod and rebuild that into LineageOS

i think the android releases >=4 has OTG host support (dependent on hardware)
https://developer.android.com/guide/top ... index.html
and it seemed there are several usb-serial implementations out there on github
https://felhr85.net/2014/11/11/usbseria ... roid-v2-0/
https://github.com/felHR85/UsbSerial
https://github.com/mik3y/usb-serial-for-android

i've yet to try them out too but i'd think it is possibly a more (most?) convenient way if one is looking for a way to interface android to BP/MM and other stm32 etc boards, the usb 'extension' effectively allows a BP/MM to work as an 'IO expander' providing access to pins / gpios, comm (uart/i2c/spi) etc providing a way out against 'non-expandable' smartphones

of course these days there is Bluetooth LE, but then that'd need the help of an extra breakout board e.g. nrf51822 or cc2540/2541 etc
the low cost stm32 BP/MM possibly still lose out to the wireless alternatives in that sense, but the built-in usb support is nevertheless one of the most valuable asset of stm32f103 etc arduino boards

@ag123

Yes. USB to GPIO etc would be handy.

Re:BLE

I have done a lot with Bluetooth, but I find on both Android and iOS, that getting thngs to work on different Android devices is problematic.
The same applies to different versions of Android and also to a lesser extent iOS.

I am not sure if USB would be any different, but its definietly worth investigating
