Observer; Power Mode; Low Power Mode - Ebyte E104-BT5011A User Manual

MAC addressmac

5.1.3 Observer

1. Command AT+ROLE=2 to select the observation mode (valid after restart)
2. After receiving the broadcast, print out all the contents of the broadcast package through the serial port.
3. The observer device cannot be connected to any device.
The format is as follows:
LEN
1 byte
Note: LEN is the sum of MAC, RSSI, and broadcast data length.
4. During this period, only AT commands are valid, and data transparent transmission is not supported.
5. All observations support RSSI, name, mac address filtering;

5.2 Power mode

The module supports two power modes: low power consumption mode and wake-up mode.

5.2.1 Low power mode

The so-called low power consumption mode means that the BLE function continues to run after the module enters
this mode, and peripherals other than the wake-up pin of the module are turned off. If you need lower power
consumption, you can turn off broadcast and scan through AT commands, disconnect all connections, and set a longer
broadcast gap, scan gap, and connection gap.
Enter low power consumption:
1. AT command "AT+SLEEP" immediately enters low power consumption mode;
2. Pass the rising edge of pin WKP, and enter low power consumption immediately after the high level is
maintained for 200ms or more;
After the module enters the low power consumption mode, it outputs "STA: sleep" through the serial port
