voltage, in order to make the calculation more accurate, mV is used as the unit, that is, 3.2v voltage value is converted to
3200 to participate in the calculation. The voltage / ratio characteristic curve is shown below. Calculation formula: p = (v
– Btmin) / (Btmax-Btmin). The actual voltage value can be calculated according to the p-in formula of the battery. (Note:
Btmax and Btmin are the values set by AT. Here 3200 and 2000 are just examples.) For details on setting Btmax and
Btmin, refer to the command 6.46 Setting, reading the maximum battery voltage, 6.47 Setting, and querying the
minimum battery voltage.
Note: This module does not need to do voltage division or other operations, just connect the positive electrode of the
battery to the detection pin (DIO_25), and then ground the module.

5.8 MAC Address binding

The E104-BT51 module supports MAC binding function. When the slave module sets the binding connection
address and enables binding, it retrieves whether the host MAC address is a binding address before accepting the host
connection request. When the address matches successfully, the connection can be established, otherwise the slave will
continue to broadcast. For details on setting command, refer to 6.25 Reading MAC Binding Status, and enabling and
disabling MAC binding. For details on setting the binding address, refer to 6.26 Reading and Setting MAC Binding.
