Wireless Prop Programming?

Hey All,

I'm wondering if I can program a prop across a wireless ethernet bridge? I have a couple of USB to Ethernet adapters that I use now for some distance programming, but I'd like to eliminate the cable. Or any other method that could program a prop within about 100 feet or so.

Thanks!

Jonathan

    The built-in bootloader will only work over a wired serial connection, but there are a variety of other schemes that will work over a wireless connection. Look at the loader used in the Spinneret and in the Propeller Backpack.

    Thanks Mike. I'll look into that. I was hoping for a out of box solution, but I guess I'll take what I can get. Just curious, why does a USB to ethernet to ethernet to USB dongle set up work, nut not with a wireless bridge? Reset line twiddling or something?

    People have succeeded programming the Propeller via a Bluetooth dongle with a DTR output pin. YMMV.

    There is an article on programming via XBee here http://www.parallaxsemiconductor.com/an007.

    Even if the USB-ethernet bridge twiddles the reset line properly, timing is critical and ethernet introduces all kinds of latencies that the process can't tolerate. It's not even the RF link so much as the ethernet layer that's the problem.

    I've successfully used a self-contained wireless USB hub with the FTDI on the far end of the wireless link, those seem to use a dedicated RF protocol that does a better job of controlling the timing.
