Struggling to find some info / Arduino IDE examples for WT32-ETH01 Wireless-tag

if you know some examples / usefull info

share it ? https://github.com/ldijkman/WT32-ETH01-LAN-8720-RJ45-/discussions

MY FTDI programmer is not always succesfull with programming = i used board 'ESP32 Dev Module' settings

STRANGE another same FTDI programmer is doing better with programming https://www.google.com/search?q=FTDI+programmer

NOW using a ESP-01 / ESP8266-01 female 8pin/2row-4pin programmer with ch340 chip https://www.google.com/search?q=ESP-01+CH340G

program = wt32-eth01 powerup with gpio0 pull to ground (better with 10k resistor?)

run / monitor == wt32-eth01 powerup = gpio0 NO connection to ground

programming mode = better put a resistor in IO0 to ground?

programming mode = better put a resistor in IO0 to ground?

If someone programs gpio0 as output and high when connected to ground blows the gpio0 pin?

program WT32-ETH01 with ESP-01 / ESP8266-01 programmer https://www.google.com/search?q=esp8266-01+programmer+ch340G

• red 3.3 Volt
• purple ground
• white TX0
• grey RX0
• Connect programmer Gpio0 to WT32-ETH01 Gpio0
• powerup with switch to PROG program == programming mode
• powerup with switch to UART monitor == run / monitor mode
