Android accessory

TurboBob — Sun, 11 Nov 2012 19:16:59 GMT

Anyone know of any support for Android Accessory mode on ANY Freescale MCU? It seems like every other mcu manufacturer has support (ok, perhaps not every one, but Ti, Microchip, Nxp all have complete solutions in their library).

It would seem like a viable market, but the task seems too daunting for a little one-man-band operation like me.

I don't want to jump ship to a PIC, but its looking like I will have to (that or NXP).

Anyone.....??

Pure speculation on my part, but I am thinking that Freescale is not seeing a large commercial market for that.

Are there any actual products that use this? I have just used blue tooth serial for interfacing to Android, and it has worked quite well, plus it is wireless.

one advantage would be powering the accessory from the droid, or charging the droid from the device. Although I'm not sure of the limitations of these within the accessory protocol.

I am looking into Bluetooth serial (since it is a serial data task that I need to perform). What interface hardware/radio did you use?

Thanks!

this is the one I have used:

Bluetooth TTL Transceiver Module w/ Breakout [RF-BT0417CB] - $13.95 :!

You can use Blue Term to test it out on Android,. It also connects fine to a PC, Windows and Linux (have not tried Mac).

You can find sample code to write your own app.

Hi,

Freescale MCU KL series which run bare can support AOA2.0, it can connect with Android device by USB or BlueTooth acting as Android Accessory.
MCU K series(e.g.K70, K60) which run MQX4.0 OS not only can support AOA2.0(USB and BT), but also can connect with PC, U disk, TF card and of course Android Device, it and play music from them.
