The AT command control: 3 GPP Rel - 13, and enhanced the AT command
BPI-BC95 NB-IoT use with arduino:
Instructions: the left aligned with the arduino VIN pin connection, connected with PWM7 pin alignment on the right.
Note:
before connection, remove the R39 and R38 resistance, or the master stm8 all IO mouth in a high impedance state, after connection, you can use BC95 development board interfaces on the power supply or USB arduino, absolutely can’t use the arduino DC seat of power supply.
In the product practice, can transform AMS1117 power supply IC and LED to be removed, with battery power directly, to achieve lower power consumption.
