I have problem with DAP 2590. Access point didn't work, after many resets. At the beginning when I bought DAP I had problem to go to configuration page. Then I reset. Finally stopped light  LAN led, and only shines Power led. I connected in to UART with this device by PuTTY and  displays an empty console without any text. What is the correct pinout UART.  What is the correct bitrate.
Is there a possibility of damage bootloader when I reseting? How I can fix this device?  Thank you for your help. Sorry for my bad language , I speak not good in english.
