2-2-1. Bluetooth specification
Using blueCore4-Ext chipset, fully compatible with Bluetooth 2.0;
High-sensitivity receive signal, small size, lower consumption
Supporting 1200bps ~ 1382400bps variety of baud rate;
Supporting SPP agreement, the maximum transfer speed is up to 3Mbit / s;
2-2-2. Use “AT” command to modify Bluetooth Module’s parameters
Notice: The following changes can’t be done by user, these should be done in factory by Manufacturer. So
