Description

T-Halow is WiFi Halow, an optimized Wi-Fi solution for iot devices, which has a longer transmission distance while providing the same transmission power of 2.4GHz and 5GHz. T-Halow is equipped with the TX-AH module, which can operate in the 730M-950MHz band, the module can operate in the channel width of 1/2/4/8MHz, and can provide a physical throughput of 150 Kbps to 32.5Mbps.

Project

There are two different versions of T-Halow, which differ in the way they are paired;

It is important to confirm the version of T-Halow you have.

-	TIME	LINK	VIDEO
VER1	V1.0 24-08-23	VERSION1
VER2	V1.0 24-04-16	VERSION2	https://www.youtube.com/watch?v=nM2GE8Imshc

Version 1 and version 2 of T-Halow use the same AT commands.

Regarding the SDK of the TX-AH module, Taixin does not provide detailed API instructions. If you want to compile it yourself, you can use this project. hgSDK

Firmware download

TX-AH model comparison

Module name	Front screen distinction	Overcertified condition	remark
TX-AH-R900P	Lower left P9, lower right P9	Can pass FCC/CE certification	Supports 860MHz to 928MHz
TX-AH-R900PNR	Lower left P9, lower right NR	Can pass FCC certification	Support 902MHz ~ 928MHz, with 915M Saw to improve receiving performance
TX-AH-R900PNR-860M	Lower left 86, lower right NR	Can pass CE certification	Support 859MHz ~ 894MHz, with 875M Saw to improve reception performance

remark:

1. The difference between the P series module and the earlier A series module is:

• The bottom left screen print of the P series is beginning with P, and the bottom left screen print of the A series is beginning with R;

• P series PIN4/5 needs power supply, A series does not;

1. The module does not have a Shield by default. The name of the module with a shield is suffix-s, where S indicates shield.

Get Start

PlatformIO is recommended because these examples were developed on it.

1、PlatformIO

1. Install Visual Studio Code and Python, and clone or download the project;
2. Search for the PlatformIO plugin in the VisualStudioCode extension and install it;

3. After the installation is complete, you need to restart VisualStudioCode

4. After opening this project, PlatformIO will automatically download the required tripartite libraries and dependencies, the first time this process is relatively long, please wait patiently;

5. After all the dependencies are installed, you can open the platformio.ini configuration file, uncomment in example to select a routine, and then press ctrl+s to save the .ini configuration file;

6. Click ☑️ under VScode to compile the project, then plug in USB and select COM under VScode;

7. Finally, click the ➡️ button to download the program to Flash;

2、Arduino IDE

1. Install Arduino IDE
2. Copy all files under this project/lib/ and paste them into the Arduion library path (generally C:\Users\YourName\Documents\Arduino\libraries);

3. Open the Arduion IDE and click File->Open in the upper left corner to open an example in this project/example/xxx/xxx.ino under this item;

4. Then configure Arduion. After the configuration is completed in the following way, you can click the button in the upper left corner of Arduion to compile and download;
