nReload Pin (Button) function：
1. When this pin is set to “low” during module boot up, the module will enter wireless
firmware and config upgrade mode. This mode is used for customer manufacture.
(See Appendix to download software tools for customer batch configuration and
upgrade firmware during mass production)
2. After module is powered up, short press this button (0.2s < “Low” < 1.5s) and loose
to make the module go into “SmartLink “ config mode, waiting for APP to set
password and other information. (See Appendix to download SmartLink V8 and
SmartAPLink APP)
3. After module is powered up, long press this button ( “Low” > 4s ) and loose to make
the module recover to factory setting.
High-Flying strongly suggest customer fan out this pin to connector or button for
“Manufacture” upgrade or “ SmartLink” application.
nReady Pin (LED) function(Low effective)：
1. OS initial finished indicator. Only after this pin output low, can the UART function be
used.
nLink Pin (LED) function(Low effective)：
1. At wireless firmware and config upgrade mode , this LED used to indicate configure
and upgrade status.
2. At “SmartLink” config mode, this LED is used to indicate APP to finish setting.
3. At normal mode, it’s Wi-Fi link status indicator. Output Low when STA mode connect
to router AP or other STA connect to it when in AP mode.

High-Flying strongly suggest customer fan out this pin to LED.
PWM function：
PWM0~PWM3 100ns period(if duty is from 0~255, then the maximum frequenry is
10M/256=39KHz), PWM4 support 800ns period.
Due to PWM pin is internal weak pull-up. So when these pins are used for LED bulb
application, suggest to add strong pull-down resistor to revent the lulb on when boot.
Note：nReload pin is also used for special function, when use this pin for PWM bulb
application and add external pull-down resistor, this will cause the module wait 1 second
when bootup(wait “space” key to etner bootloader). Contact us to provice special
bootloader in order to remove this wait time.
UART1 Debug ：
1. Is used for debug log or firmware program, baud rate 921600.
2. Can be used for communication in SDK.
