OBD II wifi module

[ktulu]

I have an ELM327 WIFI OBD II module: http://www.dhgate.com/product/good-quality-elm327-wifi-obd-ii-car-diagnostic/161047564.html
I made the mistake? to change it from Ad-Hoc to Infrastructure on it's web page.
The module is no longer visible no matter what i do.
Before it showed up in my wifi list as WiFiOBD.

Any help is wecome to make it work again.
Thanks.

(There are 2 PCB's inside, one of them is the wifi module which has a red status LED.
After powerup the LED blinks a couple of times and then remains lit. (did the same when it was visible)
I noticed that if I change my router's SSID to the same WiFiOBD, and than power up the module, the LED after it blinks goes out. So the module can detect someone else using the same name nearby, and shuts itself off. So it's doing something)

With my RS232 to wireless modem links If you effectively lock out Wireless by a configuration error, you have to go into the configuration directly through the RS232 port rather than 'over the air' configuration. There may be an RS232 port available but you may need a configuration client to reset the module to defaults.

The module is equipped with an STM32F103 ARM micro, and the USART2 Rx and Tx are routed out to 2 vias.
Other than that, it also has the Rx Tx lines to the ELM board. (these might be RS232 lines, probably this is just an RS232 to wifi adapter PCB) But what next?

OK, with the router set to the same SSID, I finally am able to reach the module on 192.168.0.10 (thanks to some help from the hobbielektronika.hu forum)
In infrastructure mode the module is trying to connect to the same SSID network, rather than creating one.

Good news.

Well done
