| Ok. I will try that, maybe 3,3v 0,8A regulator will do that job. Thanks for help. | |

| This is indeed voltage issue, pic sends every time on every startup, every second Ok to bluetooth terminal (so that self made voltage divider works) but when i try to send something on the pic, that w ... | |

| Yes. Vdd 5v and logic pins are 3,3v. So if PIC's TX-pin drives on direct 5v HC-05 RX-pin, that not last very long. Maybe i must use logic converter, but that voltage divider make job for PIC18F4550... ... | |

| Thanks for quick answers!
Yes indeed pic is driven 5v line and so is HC-05 because it is also 5v device, but that HC-05 rx line can take only 3,3v... same configuration works earlier good on pic18f ... |

| Hi!
I have problem with the pic18F47K42 and the HC-05 Bluetooth module. They both are in same voltage lines. I made voltage divider on the HC-05 RX pin that change PIC's signal 5V to 3,3V. When I ... |
