Circuit diagram AN460/D 6 SOFTWARE The complete software is listed. The reset routine (START) sets up the I/O ports including the enabling of some of the special functions available on port D. These signals (A15, A14, R/W and the P02 clock) were used during debug. The pins are not...
recoverThis example used the 2nd command mode torecoverthe HC-05 when its serial port settings are incompatible with the Arduino serial ports. Power to HC-05 must be controlled by an Arduino pin. See theRecovery.fzzdiagram for suitable connections. ...
If you connected EN to +5 V, you may have fried your HC-05 module. When connecting signal inputs (including Rx and EN) to a 5 V Arduino output, the connections MUST to go through a voltage divider circuit (as Martyn has shown in his diagrams) or you risk damaging something. Also, ...
