I have compiled an Android binary for iperf3 and inserted it into the phone's directory /data/local/tmp and made it executable (777), when I run it via adb it works fine but when I try to run it from a Shell Script in my macro I get an error "can't execute: Permission denied". I have applied the adb hack but it still returns the error. Any ideas as to whether there is a way to do this? Or is there another way of running an iperf3 test autonomously from a macro. Thanks
