ma ktos pomysl ?

a nie wiesz czy  w 4.21 musze ?? jak to sprawdzic ?

możesz wytłumaczyć mi to:
The v4.23 uses the standard TP-Link pinout, however the TX pin is not connected to the CPU. In order to make the TX line working, the two points on the bottom side of the PCB must be connected with a small wire. The pin at the SOC is labeled TP18, the one at the serial connector is labeled TP28. T he RX line is 5V intolerant! So the connection needs a 3.3V RS232 level shifter. Pins on the connector on the photo are TX-RX-GND-3V3(VCC) (from left to right).

mam zrobić mostek TP18 z TP28 i TX ??

VCC podpinam pod 3V z tego konwertera ?
