Well, that's the complete PDF document, what pages did you reference and what commands did you use ? Were the commands used using the USB-ttl adapter or via WiFi and AT+ command mode ?

Sure, here are the main infos that saved my a... : go to page 121 and if this is not sufficient to reset to default, use command instruction table in section 6.2.1

I did that using the USB ttl since I could not access the wifi card at all.

I finally got a connection btween EZB and wifi card but it did not seem to receive any command... and the connection took forever to establish...

I don't know if you knew that already but I found it was worth saying it in case you didn't : don't use the same tcp port for accessing the UART wifi web interface and the uart wifi server mode. In auto work mode you must define a different port than the one used in the advance menu. They call it "web server" while it is just the web service which is not the tcp to com service. These are two different things. I'm not 100% sure of what I'm saying (for the difference of ports, not for the difference of services) but I know for sure you cannot use the same port for two different services and this is the only way I could have the autowork mode operational. Otherwise it just doesn't seem to connect to my router.

I sent an email to the tech support group that sells this WiFi unit and asked them if there was a hardware wiring solution to force a factory reset on their device. I received this response:

There is no method to do hardware reset.

So, the only way to perform a soft reset is to gain access via WiFi or USB to the circuit board and send the AT+ command-(USB) or button click-(Web page of WiFI)

I've also noticed that sometimes when populating the various pages of the WiFi device some fields get populated with invalid values which will then cause issues with establishing a connection to the board. Double check all values in every field before using the "save" option to flash the WiFi board.

There is a method and it is described in the doc... the guy who answered you just didn't want to bother with his own ignorance. You just need to send a low digital signal into the pin 4 for few seconds then you gain access again through USB/TTL via terminal debugging and can send the restore to factory defaults AT+RSTF command...

It shows anyway that this company has no customer service. I'm facing the same problem with sainsmart, they just don't know their products because they are not developed in their country bu probably in India or Korea.

Ok now I'm still struggling in trying to connect EZB to wifi. I created the virutal com port but it doesn't want to connect to it. I'm receiving this message from EZBldr :

Attempting connection on COM3 Comm Err: The operation has timed out. BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.Connect(String hostname, String tcpPassword, Int32 baudRate) Disconnected

Any clue ?

Time out errors would suggest that the connection from the PC to the device is broken. Ensure the WiFi module is connected to the WiFi network Ensure your virtual com port is set up correctly, with the correct IP etc.

If all else fails, reboot the PC, power cycle the EZB and try again, Windows has a habit of just not working sometimes.

elfage that is how i reset my wifi is with the AT+ commands but but this time it won't work so i took a week off and did not touch it at all. I will have to try it now.

as for the errors i would get the same thing. Rich is right,try to reset and if that does not work i changed com port and that would help most of the time(don't know why)
