@Doc... good tip, thanks!

@Richard.

Thanks buddy. I'm actually using jumper cables instead of a mini din and the connection is good. Speak to you tomorrow.

@Doc.

Sorry my friend. I have to admit you lost me there a bit. Could you elaborate a little. Are you talking about a "Y" cable (pin5 and pin 6 to where?) or jumper cable from pin 6 in to pin 5, and what script would I need to use for an "On" button? confused

I'm discussing the electrical connection of your comm cable that you wire from the UART to the Roomba. There are two pins used for providing ground (6 and 7) pin 5 which is next to pin 6 can be strapped together and then the same ground lead is sent to the EZB controller via your com cable.

@Doc.

Right, just to confirm, it's a "Y" cable I need. Join pin 6 and pin 5 together, and than connect both to the UART ground pin on the EZ-B. Gotcha. Thanks

Thanks for that Doc. Got it working now. When I hit the Off button on my mobile control, it will automatically turn back in again in a time frame anywhere from15 seconds to just over a minute. Just curious though, is there a way to script a button to do this to maybe speed up the process? Not to bothered if there isn't, just wondering.

I'm not aware of any way to accomplish that action unless you want to add a relay to short pins 5 and 6 together when the relay is operated.

@Doc.

Cool, no worries on that front. I don't think I'll go the relay route as I'm happy with the auto switch on. Again many thanks for that. It's a useful little hack. Just want to sort out switching on the sensors while under manual control and I'm all set.

One final question you may be able to help with. I've looked through the manual but couldn't find anything that could help. Is there a low battery warning command that can be used? I'm thinking that if there was, while the Roomba's under manual control and the batteries voltage drops to a point where it needs charging, I could insert a script to where it would take over, say (using a sayEZB script) "I need to recharge my battery", seek the docking station, and recharge.

Is that possible?

@Steve... See post 50... this script does work (LOL) it monitors battery voltage and when it drops below a certain voltage (in this case 13.9v) it instructs the Roomba to seek the docking station...
