esp-wifi bench server on Android

This is https://github.com/esp-rs/esp-wifi/tree/main/extras/bench-server for Android.

Needed

• android-ndk
• cargo-ndk
• toolchain installed (rustup target add armv7-linux-androideabi)

How to compile

set ANDROID_NDK_HOME \tools\android-ndk-r26c
cargo ndk --target=armv7-linux-androideabi build --release \tools\adb\adb.exe push target\armv7-linux-androideabi\release\bench /data/local/tmp \tools\adb\adb.exe shell

In the shell

cd /data/local/tmp
chmod +x bench
./bench

or just use run.bat

How to use with the benchmark

Start a hotspot on your Android phone. Figure out the HOST_IP (e.g. connect with dhcp example and use the gateway address). Then use bench or embassy_bench.

Why

My idea was to put the phone and the ESP32 into a shielded box but I haven't found anything that shields signals good enough. Still I can put the two devices aside and get less varying results.
