Ez-B V4/2 Comm Upgrade And Ez-B Iotiny

I would like to know if the comm bords of both IoTiny and the new v4/2 are the same? If yes, why does the v4 upgrade cost more than the IoTiny
Thanks.

Actually, there is a firmware upgrade available, it is just not critical that it be the first thing you do, but you might as well.

Are there any release notes that say what the newer v4/2 firmware are ? I've been looking over the website and can find little info about updating any firmware. I know by asking in this forum where I can find the update utility (in the EZ Robot folder the residues on my computer) but there is no documentation in that folder or anywhere on the EZ Robot web site I can find on how to do it or what it will change.

As awesome as EZ Robot and their produit is, I continue to to be frustrated by the difficulty of finding information on this website and searching the community history for answers. *stress*

No release notes were posted.

To do the firmware update, just start the updater application and follow the on screen instructions. Super easy (or should I say "EZ"). Works in either AP or Client mode, and just like ARC, it can find your EZ-B from its broadcast, so you don't need to know its IP address.

Dave, sounds like you are using Windows 8+. Windows 8+ does not put icons on the start menu automatically, and you must do it yourself. There's an All Apps button in the start menu to list all installed apps.

Find out more with a website like this: http://m.winsupersite.com/windows-8/windows-81-tip-find-your-installed-apps

Once you press that All Apps button, you will find the ez-robot section and it contains ARC and the firmware upgrade programs.

Remember, a long time ago you asked how to add ARC to the start menu? Well, that's because windows 8+ changed everything.

Please do not blame ez-robot for the changes to Windows 8+ operating system. You do not need to navigate through the C:\ to find programs. They are listed (hidden) in Windows All Apps start menu.

Also, there's no reason to upgrade, otherwise we would have told you to.

As Alan said it really couldn't get any easier to update the iotiny or ezb... Saying that however maybe it would be possible to have an auto firmware updater? Something like when ARC connects to the ezb you can have (the option to) it check the firmware version on your ezb. Then if an update is required it can do it automatically from there by launching the updater software... Just a thought...

Latest software operates like the v3 informing you of an upgrade if applicable. You do not see a message because upgrade is not required.

Understood and thanks guys. I am using Windows 10 but am finding that as the Win versions move forward I'm having difficulty keeping up with all the changes. The added menu items looks like one of them I guess. Looks like technology is starting to pass me by. *tired* I started out by using Windows 3.3 years ago. *eek*

Just for the record I don't blame EZ Robot for anything Windows does. Even though I don't know what they all are, I completely understand the challenges you guys face from version to version and working with Windows inherent quirks. I was just stating that I found it frustrating at times looking for information using the search function on EZ Robot website. For example I was looking for anything to do with updating the V4 Firmware and really couldn't find anything current. In defence of the website search function this could be because I couldn't find the proper combo of search words to use or as you all pointed out there wasn't anything new to find. ;)

Many thinks again and my apologies for opening a can of worms. :)

Dave,

For complex searches, you can use Google and specify the site so it only searches the forum. Works much better, particularly when there are multiple words or a specific phrase you are looking for.

The format is:

Code:

Yep, same here Dave. No joy searching for v4 firm update in the forum.
Haven´t had time to install the v4.x/2. Hope to do it tomorrow *mad*.
Thanks guys.
#25  
Thanks Alan. Now I remember you posting this a few weeks back. Sounds like an excellent idea.

Which of course, without knowing this trick, you probably would not have been able to find;)

Not sure if this is the correct thread to post this in but it does have to do with the IO TINY Board. I was thinking of using an ESP8266 on my robot along with the new EZB-V4/2 controller. They would be both powered up and online at the same time. They will be in fairly close proximity and was wondering if the would present problems with the wifi operation of both controllers?

Also I will only be controlling a couple of relays with the IO TINY Processor Board. No camera and just using a couple of digital lines. I was wondering what the power consumption is when the IO TINY is up and running with just the wifi active. Would it be comparable with the ESP8266 processor?

I find that the ESP8266 processor has some serious wifi connection problems and wanted to check to see if the IO TINY would fit the bill using only the wifi connection and a couple of digital outputs? :):)

Hi @rbonari

I would definitely try to separate your WiFi controllers as far as you can from one another. In the past, with Bluegiga modules, we've seen considerable radio communication interference from one wifi module to another at a foot away from each other.

The IoTiny board typically draws 70mA @7.4V with no other peripherals connected.

Sorry, I don't have any current draw specs for the ESP8266.
#29  
Thanks Jeremiah,

Are the Bluegiga modules the ones used in IO TINY and EZB-V4/2. Am I correct in assuming from what you said in previous post that there would be considerable issues with the IO TINY and EZB Controller when located within about one foot of each other?

I want to locate both controllers on irobot create 2 so I would probably need to construct a shelving system to separate the controllers. Any other ideas on minimizing any interference would be much appreciated....Rick
#30  
I'm not promising the same results but I have two V4 EZB's (not the new /2) sitting within 6 inches of each other and have no issues that I can tell. Both attach to my network in client mode just fine and operate perfectly.

Thanks Dave,

That surprises me, but I'm glad it works for you:) It may have to do with the strength of your router.

@rbonari The slash 2 and IoTiny both have the MxChip module on them. I haven't had a chance to do some "minimum distance of separation" tests. Maybe someone in the community has.

Would you be using client mode? [Both modules connected to a router]
Synthiam
#32  
It shouldn't surprise you because it's in client mode. Client mode uses the same wifi channel and the communication of all clients is synchronous, meaning they each take turn sending/receiving.

If the ez-b's were in ad-hoc mode (access point), then i would be surprised about good performance if they were all on the same channel.

A channel is a frequency the wifi "talks" on. When there are too many devices on the same channel, there will be interference.

If you were to use a bunch of ez-b's all in access-point (ad-hoc) mode, then i would recommend following the FAQ which explains how to use Wifi Info to display available wifi channels and saturation here: http://www.ez-robot.com/Tutorials/FAQ.aspx#9

For best performance of multiple EZ-B's, client mode is the best - unless your network is saturated with wifi communication of too many devices. Again, this doesn't mean wifi frequency interference, this is device communication over the single wifi channel of client mode.
#33  
Thanks DJ and Jeremiah,

I will be using them in client mode and it sounds like this is a good thing. I will go with the IO TINY when they are available ( any dates?). I would like to order two.

The IO TINY sounds like a way better solution than the esp8266 for small IOT applications etc. The esp8266 has some serious WiFi connectivity issues anyway.

Jeremie, you mentioned with no other items connected to the IO TINY that the current consumption is about 70 MA. Is this true when WiFi is on and communicating in client or AP modes?......Rick

@rbonari

Well I did some quick measurements and found that it doesn't matter if the IoTiny is connected via AP mode or Client the current draw is the same. With these more recent measurements I found that it's actually ~50mA of draw (without peripherals).

If you started to play audio it would go up significantly higher (depending on volume) but as-is the current draw is pretty low.
