I'm not sure if there is some similarity with this issue and my previous post but just in case I'd rather make a separate post. I'm trying to simply reset my EZ-B from Client Mode to default AP mode and it is not resetting. Currently the light is blinking green after I have reset it and I don't hear any verbal messages. I don't hear the message that says it has reset.
I've check the Connection & Troubleshooting page, I've checked the tutorial on How to Connect Your EZ-B v4 to your computer, Resetting Your EZ-B v4 lesson and many pages of Forum posts but not seeing how to resolve this issue. It was working fine yday but since I'm having issues my wifi adapter I just want to reset to default along with my other EZ-B controller. Suggestions appreciated. Thanks
The distance of WiFi signal is an arbitrary measurement due to an unknown number of attributes in your environment. It is absolutely impossible to predict the wifi distance because there may be significant interference in your environment. For example, wifi saturation of other devices, microwave ovens in nearby dwellings, power lines, and even the building construction material.
Here is a good FAQ about WiFi: https://synthiam.com/Tutorials/FAQ.aspx#9
As for your second question, the motors will continue to operate when the ez-b disconnects because the last signal transmitted from the ez-b maintains in the HBridge. This mean the motor driver (hbridge) continues to operate with the last instruction it received.
If i told you to walk forward, and i died... you would continue walking forward for ever because i'm no longer present to tell you when to stop.
There are quite a few threads with discussion on this topic. How to stop the motors when the ez-b disconnects. It can be done by creating a small circuit which monitors the ez-b led status, but that's not an easy job and i highly DO NOT recommend it.
Add a safety switch to your robot so if it does disconnect and "run away", you can easily flick a switch which cuts power to the hbridge and stops the wheels
