Yea its a current issue. Since I have a day and some time before my local hobby shop opens I thought I'd do a little amperage measuring. The USB to TTL puts out roughly 324mA to the TLG. I measured the amperage of three different power supplies I hooked up to the EZ-B: my 12V power supply, my 7.4V 910mAh LiPo and my 11.1V 3Ah LiPo. All of these power supplies allowed for 210mA to 220mA. The manual for the TLG states the operating current to be around 300mA. So there I go reason for it turning on sometimes and not working others. I'll just grab another 7.4V LiPo and parallel them.

Thats elechouse same company and everything I just don't see any drivers for creating a virtual com port out of the Wifi TLG. DJ said it installs its own drivers but the only drivers installed from those documents are for the usb to ttl controller. I must be missing something.

I did it if i remember correctly with the following steps

connect the wifi module with te serial usb. install the drivers and it assigned a serial port you can see in the device manager ( windows )

connect with the program "uart-wifi" to that com port. That did it for me.

don't forget to restart ARC

@Pabi!o,

Are you saying that uart-wifi installed a comport on your system that ARC sees. I have my TLG configured and it is in auto work mode. I can get to the web page on the device and make any changes. My problem is that I don't have a virtual com port on the host. If you go into device manager in windows...you must have another comm port there that came from somewhere. I don't have it. All I have is the prolific drivers I used to communicate with the TTL device?

Do you have to keep the uart wifi program running?

Glad you got it running....like orwnic82...I am also missing something.

@Pabi!o,

How did you get the TLG to run off the 3.3V line I tried my 2Cell LiPo and it draws 206mA which is a hair short of 300mA for the TLG to run, So I paralleled in a 2nd and it still draws the same amount of current.

Hi Pabi!o

I am running mine off the 5 AA battery pack right now. The TLG works with either the 3.3 V or the 5V with no problems. I did notice that if I ground it to the TTL header ground it does not work (as there is something going on there as the light on the TLG glows very faintly and does not connect to my Access Point.

I am still having problems with this device. I cannot even get the TTL to connect up the board direct using the USB. I have the latest firmware but still not able to connect to ARC....how is yours working out?

Also, how did you get yours out of auto mode? When I try to turn it off in the web page it does not save and stays enabled. Hope this helps you with your troubleshooting.

Yea I sent over the command +++ for some reason I had to use the arduino software terminal to send the command, Hyperterminal and c# application didn't work, weird. I'll see about changing the gnd but other than that it is a current issue. I've waited for another LiPo to see if it would increase the current by paralleling them but the current stayed the same. I haven't got to check if I can connect through a virtual com port yet though trying to get the module working off the ez-b power source.
