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 V8 config mode, when in SmartLink V8 config
mode and short press this button again to go into SmartAPLink and SmartBleLink
config mode, waiting for APP to set router SSID and password, config module
connect to router. Recommend to use SmartBleLink BLE method config.
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.
