Hey guys, this is short and simple....just wanted to know if this is a common problem when running the EZ-B on lower voltage!
I am running my EZ-B on 6Volts and I experienced that it gets disconnected from my Wifi network at random times! It tries to reconnect, says it succeeded and drops out right after. This happens for a while, then it is establishing its connection and it stays connected!
So is it because the EZ-B is running on lower Voltage, it is only the Wifi connection which gets lost...there is no brown out, and also it happens while the robot is not moving at all, I am just working on parts and the EZ-B is sitting on the table not doing anything!
Or could it be that there is some interference from the Power Supply, it sits on the table right next to the EZ-B?
Any ideas?
The bec has a cap on the 5v side which may be why I don't see any issues with my setup.
@Alan,
That idea reminds me this one:

Can be interesting add on for the JD when doing complicated moves (more servos working at same time)
The power supply is a good product:

I've used for a few setups (multiple leds) and raspberry pi & a lot of usb devices connected.
I need to test the EZ camera again with 5V/10A, it's very strange because the camera gets 3.3v from the EZB, so if the EZB can work with 5V i don't understand why the camera does not work, must be my mistake.
@Alan,
Just re-checked, the camera works with 5v , it was a software issue, the camera object recognition crashed (null reference) and the camera stops because is too fast i got the wrong idea.
but servos they start holding the position, but 1 second later they stop holding the position.
If the camera crashes with null reference, that means it went away. either the wifi disconnected or the camera stopped transmitting.
If you believe this is wifi related, check the faq which is located in the learn section.
If you're browning out due to using incorrect power supplies - there's dozens of threads pointing to correct suggestions.
Hey guys, closing this one...thanks for the help! The issues are still remaining, I will if I can get something solved I will let you guys know. Thanks for being with me on this one!
Hey, just a little update on this topic... @DJSures just told me there is some info and help covering Wifi connection problems in the FAQ section of the EZ-B documentation!
I will try a different setup soon and will give you guys an update if I manage to solve the problem!
I checked my router and the Wifi channel was cluttered with Networks, I just changed the channel and I guess this should solve the problem...lets see!
By the way did changing the channel help with your disconnect issue? Listening to the posts and knowing you were running lower voltage my first guess would have been voltage drop causing the issue. Unless you are running a lithium based battery which handles high current draw you will always have around 2 volts drop when current is drawn around 1C or higher.
