Then we uploaded the basic example sketch 'Wificlient' using Arduino IDE , the upload was successful .
now we made GPIO 0 high to put the chip in running mode and powered it , but the board isn't running the uploaded code , there is no output on the serial monitor .
The power supply is external source.
Could someone help with this issue . thanks
flyingbaloon:
yes , i have (10k)pull up on GPIO 2 , CH_PD , RESET , and while booting i connected GPIO0 to GND , in running mode i pull up(10K) GPIO 0 .
when i connect GPIO to GND and upload sketch it uploads ok . then on the serial monitor i could see
nvnvNvvnvnvnvnvNN etc ., (according to the wifi client sketch the serial output is supposed to be "......" before connecting to wifi)
when i connect GPIO to VCC and restart the module there is no serial output .
I can't find it in docs, but I think to remember, io 0 should not be connected without resistor
