Hi Miklos.As usual, thanks for your replies. I take into account the amount of energy used by MCU, but, in this case, the sum is 17 mA (transmit) + 8 mA (processor in full operation) = 25 mA, while I got 20-21 mA. So, the only idea that comes to my mind is that the processor doesn't work at full operation. What do you think so?
