2.4. LED
Module provide LED output and can display module working status by LED status. Connecting to 1K Ohm
pull-up resistor to 3.3V is recommended. User can also drive LED by triode to improve LED luminance.

2.5. Reset and Reload
nReload: nReload pin can connect to external button or configuration pin. Press button 1s to 3s to enter
simplelink mode, press over 3s to restore default settings. nReload pin should connect to external 4.7k-10k
Ohm pull-up resistor.
nReset: Resetting the module and taking effect in low level. nReset pin connect to internal 100K Ohm pull-up
resistor to 3.3V. Press over 0.5s and release to reset the device.
Circuit diagram as follows:
