Changing the UART ports is a good solution. Thanks for sharing your experience.
]]>Hi, are you sure you have got the ES900RX and not the older ES915RX? ES915RX didn’t have the WiFi update possibility, but ES900RX has. Bot versions 2.4GHz and 900MHz have WiFi. RX has ESP32 chip (ESP8285), which does have WiFi connectivity.
If you fail to make WiFi update, then you can try to connect the receiver to the FC and try Serial Passthrough method.
Thank you very much for your comment! Guide is not perfect, a lot is missing and it took way more time than I thought to write it.
