|

|
* - to set up ADB over Wi-Fi with custom roms you typically can do it from: Android settings -> Developer options
|
||||||
|
* - for other devices you first have to manually connect over USB and enable Wi-Fi as shown here:
|

|
* https://developer.android.com/studio/command-line/adb.html

|
* python + pyserial + https://github.com/pyserial/pyserial/blob/master/examples/rfc2217_server.py
|

|
* for developing this test it was essential to see all data (see test/rfc2217_server.diff, run python script with '-v -v' option)
|
||||||
|
* - all suppported usb <-> serial converter

|

|
* - some tests fail sporadically. typical workarounds are:
|

|
* - reconnect device
|
||||||
|
* - run test individually
|

|
* - increase sleep?
|
