2.8. Parameters Configuration
HF-LPB module supports two methods to configuration parameters
: Web Accessing
and
AT+instruction set.
Web accessing means users can configure parameters through Web browser. When HF-LPB module
connected to wireless network, parameters configuration is done on a PC connected to the same
wireless network.
AT+instruction set configuration means user configure parameters through serial interface command.
Refer to “AT+instruction set” chapter for more detail.
2.9. Firmware Update
HF-LPB module supports two on-line upgrade methods:
Webpage Wi-Fi Upgrade
Remote
Upgrade
Webpaged based Wi-Fiupgrade,please refer to 3.1.8 firmware upgrade page , user can upload
firmware file from PC to HF-LPB.
Remote upgrade: TBD
Notes:
please contact with high-flying technical people before upgrade firmware, or maybe damage
the module and can’t work again.
2.10. GPIO Function
HF-LPB module can provide maximum 12 GPIO pins, which include 2 A/D analog input pins, 3 PWM
control pins, 2 Pin sleep control pins, 1 WPS pin, 1 RTC pin, 1 USB 5V control pin, and 2 general
GPIO pin. All these pins can be customized as GPIO pins if these functions are not required. As GPIO
functional pin, user devices can read/write GPIO pins status through AT+instruction set.
Table 8 HF-LPB GPIO Pin Mapping Table
When module works at GPIO mode, PC and other equipts can setup connection (TCP/UDP) through
WiFi, then read/write GPIO information through command.
