1. BLE4.1 devices operate in the unlicensed 2.4 GHz ISM (Industrial
Scientific Medical) band. BLE4.1 wireless technology has 40 channels (3
broadcasting channels, 37 data channels), each channel spacing 2MHz,
over the entire operating frequency range: 2.402-2.480GHZ. A frequency
hopping transceiver is used to combat interference and fading. The
modulation method is GFSK, the output power is 0 dBm, and the maximum
transmission range is 10 m.
2. The MBP69SN device uses BLE4.1 to establish the connection, with
our device acting as a peripheral. The device will passively respond to
the app’s connection request and establish a connection to the app.
Once MBP69SN has connected to the app, the device will no longer be
