Hi! A couple of years ago I built a IOIO-based anemometer which has run on an Android 2.3 device (Huawei Ideos) over ADB more or less 24/7 without a problem. Unfortunately the phone was stolen so I need to replace it with a new one. I have a Nexus 4 running Android 4.3 which I'm trying to connect but are facing some connectivity problems.
>From reading posts here I understand that from Android 4.2.2, ADB is not longer possible to use so I need to move to AOA (Bluetooth is not reliable in my application due to low bandwidth and high latency/jitter and the fact I'm not using firmware PulseInput). Since my IOIO app was not built with IOIOAccessory lib I need to rebuild it (unfortunately I don't have my development environment so I need to set a new one up). Before doing that, my first step was to try to connect the IOIO-OTG board with the Nexus 4 phone over AOA and use the IOIO Hardware Tester app (latest from Google Play) to see if I could get that to work. *I don't have any previous experience with AOA but I reckon I should get an AOA popup when the IOIO board is connected to the phone. Right?* However, there is no popup. This is what happens: * When I connect the IOIO-OTG board to the phone the charge icon is lit (trim pot. at its max) but no popup is displayed. * Using a USB cable, the latest IOIO Hardware Tester app (which according to the description supports AOA) won't connect. * Using a Bluetooth adapter, IOIO Hardware Tester app connects and I can toggle LED on/off. This is what I have tried: * Several different power supplies (ranging from 5 to 12 VDC). * Several different USB cables. * Turning Developer Mode on/off (not sure this matters when USB debugging is not to be used). My IOIO hw/sw versions: IOIO board: IOIO-OTG SPRK0020 IOIO bootloader: IOIO0400 IOIO firmware: IOIO0500 Any ideas on how to debug this?
