Using LilyGo T-Halow - ESP32 Wireless Network instead of Ethernet Network

[f2ka07]

I recently acquired two T-Halow modules and configured IP addresses through the Ethernet bridge. However, when I disconnect the Ethernet cable, they lose connectivity. This is expected, but can we connect the T-Halow devices to a wireless network instead of an Ethernet one? For instance, can T-Halow get wireless LAN connectivity from ESP32?

You can try to use AT+VERSION=? to check the firmware version of the TX-AH module. The firmware in bridge mode is VERSION:v1.6.4.3-xxxxx. If it is another version, please replace the firmware chip that comes with lilygo to see if it can help you solve the problem.

here is a demonstration video:

I got stuck because I encountered another issue with one of the T-Halow devices. It doesn't respond to the AT command. The only output it gives is as below. Sometimes the output comes from USB C and other times in the other USB. What could be the issue?

ESP-ROM:esp32s3-20210327

Camera init failed with error 0x105Card Mount Failed

If you buy the following version of T-Halow and replace the bridge flash chip in the package, you need to use Micro-USB (that is, position 2 in the figure below) to send and receive AT commands;

1. Type-C : Used to supply power to the device
2. Micro-usb: Connect the TX-AH module for debugging

If there is still no response after sending the AT command, contact the after-sales service;
