Please refer to this video I put together. Since you’ve mentioned micro usb port I am making the assumption you have the older hardware. Not all applications open and communicate correctly with the micro usb port which is what you need to connect to for the purposes of sending AT commands. You can likely find the windows version of this application and follow along as needed, but I used Linux. |
|
The label in the hardware says: |
|
Now the microUSB port prints, I've 2 device, one with flash chip replaced which came in the box. |
|
And it's print, every 2 seconds. |
|
Yep, use the chips provided that came in separate bags. I can’t speak to the hardware confidently as you’re mentioning you have a micro usb port. I have two hardware models, the older ones that had micro usb and usbc ports and newer hardware that has just usbc port but also has a mode switch for ap/sta and a pair button. If you’re now seeing output like you’ve shown above on the micro usb port, you should be able to issue AT commands. |
|
If you’re simply trying to use them to setup a wireless bridge mode, meaning you can plug a laptop into each one and be able to ping from laptop to laptop, then check out the video I shared. You should be able to give AT commands to make one an AP and one a STA and then initiate a pairing process once. Once complete, you’ll be able to communicate across. If you’re trying to setup one of the other modes, you’ll have to refer to the info lilygo provided. I’ve only focused on bridge mode so far. |

Here it is. |

Yep, I have that version too - just the 900mhz one instead. The video and steps I mention above should assist you assuming there’s no problems with the chips you inserted. Pay super close attention to the markings and dot on them as I accidentally briefly put one in to the seat incorrectly. Since you’re seeing output on micro usb you of course have if in correct. |

I'm using |
|
I've 2 devices, one replaced flash chip came with bag and another as it's out of box. The log is only printed from the flash swapped device. |
|
Each device should’ve came with a chip in a bag, based on my knowledge of the older devices like you have. You need to replace the flash chip of each one with the chip in the bag. Then perform the steps according to lilygo images or my video. I don’t see in any of your screen shots above where you are issuing AT commands. |
|
Okay. I replaced flash chips for both devices. Here is the command I've issued and received no response. *** local echo: yes ***

Okay. Seems like AT command is responding. |
|
Yep that shows you it’s working. If you refer to the video I linked you to it shows you all the steps or issue the commands per the documentation. For example on 1 on 2 on both while leaving both powered look for successful pair then on both |
|
The behaviour is related to |

You can then plug one into your home router, for example, and plug your laptop into another. If everything is working, you should get DHCP from your home router. |
Interesting, yeah I use what I showed in the video as that worked great for me. |

Just a quick question @alphafox02 - Did you managed to work with WiFi STA and AP mode building a bridge instead of the Ethernet connections? |
|
Please explain more. I was mainly focused on the bridge from AP to STA or STA AP STA and being able to have devices plugged in via Ethernet communicate across. In those configurations things have worked. But in both configurations, the bridge is built across the Halow wireless bridge. I’ve also tested multiple pairs on drones, but that gets a little more complicated. |
|
Here is my thought. I'm planning to setup first t-halow (TX-AH) as an AP and the same as an WiFi AP. And the second t-halow (TX-AH) as an STA with WiFi AP. If I connect first WiFi AP to device 1 and second WiFi AP to device 2 and assign IP address, will I be able to ping each other? |
|
Setting this will make the esp32 as STA and join to the network? https://github.com/Xinyuan-LilyGO/T-Halow/blob/master/docs/AT_cmd.md#atssid |
Hello there,
I brought T-Halow and tried to communicate with TX-AH module via AT commands with microUSB port. But failed.
Do I need to flash the firmware to do so? Or is there a way I can communicate via ESP32 out of the box?
