- Sat Nov 08, 2014 11:45 am #2334 Hello everyone,

I just received my ESP8266, and wired it up.

Serial comms with terminal work ok (thru' a home-made MAX232 board and an external 3.3 supply).

I also added a decoupling cap of 10uf across the module's Vcc and ground.

Now, I can see the module on my Android.

COULD see the routers (mine, and ones in the vicinity) with the AT+CWLAP.

Could connect with my router after specifying SSID and the password.

BUT, after that, AT+CWLAP no more lists the routers around; module seems to hang with a "busy now' response to any query.

All other AT commands still work.

Wonder what is happenning? (Module is connected to my router, confirmed that using AT+CWJAP?)

Wonder how to erase my router from the module's eeprom? That might make the AT+CWLAP start listing the routers around again.

Any pointers would be highly appreciated!

I had inadvertently given a wrong password for my router, and the module would keep on trying to log on continuously.

Used the AT+CWQAP, re-defined my SSID and password, and it works as it should.
