Power supply: 3.6V current peaks of up to 2° and a maxximum voltage drop of 300mV durino transmission burst. Local power source feeds the Q2501 module and the PIC 18f2620.
Connection MCLRE pin – Diode –R 11Kohm – Vcc. I use one breadboard.
Hour we come to the good news: inserted condenser from 0,1 uf. They are some hours that software turn without restart. The strange characters between the PIC and the PC are passings also. Thanks. Perhaps resolved problem
