UPD: Attached the example of received bytes from UART buffer. All the shown bytes were sent to ESP32 as a single pack of data. --END-- line represents the point, where Serial2.available / Serial2.read think the Rx buffer is now empty. After interracting with Serial port (UART with PC) (for example s...

The command transmission from ESP32 works fine, but the problem appears with the response data reception. PGA460 responds with known number of bytes every time. ESP32 receives them all, but the...
