Operation
1) Power on Reset
After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times. The total reset
time is around 2s, as below:
Note:Contact us to customize if you want to shorten the POR time.
2) Sleep mode
After Power on Reset, the module enters into sleep mode when CS pin is pulled low. In this mode,
the current consumption is very small. In Sleep mode, the module can’t do any communication and
cant’ be set even Set Pin is pulled low. All the parameters will be kept unchanged in Sleep mode.
User can wake up the module by pulling high the CS Pin.
