Hi everyone,
I got my ez-b 2 weeks ago. I was able to successfully connect it to my computer, although it would sometimes take several attempt to have a successfull connection. But since this morning it stops connecting. Both status and bluetooth LED are flashing but it won't connect. I tried everything: I made sure the power supply is ok, I reinstalled ARC, successfully Paired the EZ-B with my computer, but it's still not connecting. Could someone help please?
Nick
Hi Nick,
Please check out the CANNOT CONNECT thread in the General Discussion forum, there are a few suggestions there to try. The fix that help that specific user was to reseat the bluetooth module that sits on top of the EZ-B. I also found that I have to reset the bluetooth module every now and again when I just start up because I have a bunch of servos hooked up and they cause huge current spikes on initial power up and seem to cause power interference with the bluetooth module. (Seems to put bluetooth module in a constant state of reset, the red LED doesn't even come on). All I do is power up my bot, unplug and replug-in the bluetooth module, wait for the blinking red LED and then connect, works for me everytime.
Hello, Skater_j10 and Nicolson. I am sorry to report that my problem in the thread CANNOT CONNECT! still persists. The resetting of the Bluetooth is a good temporary fix, however I still can't hold a connection with my computer. Lyron and I had another thread about this problem here, but so far we have had little/no assistance.
Hi skater_j10 and TXTCLA55, thank you for your prompt replies. I did try to reseat the bluetooth module but with no success: the bluetooth LED will stop blinking for 2 seconds and resume again with the cannot connect message. I included this video to show you what happened.
Mine does nearly the same thing. I think the problem must be in the ARC or the code within the EZB. Unfortunally we have no way of fixing this problem till DJ comes back. stress
Have you you ever gotten the EZB to successfully connect to the computer for more than 5 mins? and what happened after connection?
Yes TXTCLA55, I was able to be connected for more than 2 hours, but before it stopped connecting permanently I noticed that some servos that used to work properly would no longer respond while others worked ok.
I have noticed that the small voltage regulator(L4931), near the power adapter between the 2 small capacitors would get red hot even without load. do you experience the same thing? Here a picture showing the voltage regulator:
From the sounds of things it looks like you might have overloaded your board. How many servos did you have attached? I never really experienced a heat problem like that, normally mine is only on for less than 5 mins.
How much power were you connecting to the EZB?
Ignore this double post
I am using a 8.4 volts, 4000mah, NI-MH battery pack with 9 servos attached.
It seems that the less than 5mns problem you're having may have to do with the battery pack you're using. I used to have the same problem using the small battery pack shipped with the unit. What is the voltage and mah of your battery pack?
When it comes for the overheating of the voltage regulator, it was happening from day one with no servos attached. Would you please touch yours to confirm if its normal to be that hot. be careful if yours is as hot as mine you may get burned!
If it's unusual to be that hot I will attempt to replace it and see what happen.
