Note: A key programming , ESP8266 V0.9.2.2 version of firmware
is changed .
Please add QQ group 120,693,138 in order to obtain more detailed
information .
1. Please MTDO and GPIO0 to a low level , GPIO2 placed high.
If your module does not MTDO, please at least
GPIO0 placed low.
GPIO0 at low level programming model is the
high level run mode.
Attention must use the pull-down resistor to
set the level , not directly connected to VCC / GND.
2. Please resetting ( RST refers to low-level pulse ) or re-
enter the programming mode on power .
3. Please do not use USB to TTL power leads , use a separate
power supply .
Power quality related to the module is stable
, there is a problem please check the power priority .
4. After successful programming , please re-power . Module
change the baud rate value 9600 or your last set .
5. Writing aborted , re- power programming.
Further ALL
GPIO should connect to VCC/GND with 3.3K resistors to avoid excessive current.
