I looked at pages 5 and 6 of the manual and sent the commands exactly as they are described and got no response from the unit. What encoding is used, ASCII? I have the following settings:
Baud rate: 115200
Data bits: 8
Parity: None
Stop bit: 1
No carriage return/line break after commands
UART TX → Board RX; UART RX → Board TX
Can you send me the command set in HEX format? Not the text. For example, if I assume ASCII is being used, if the command is "test 100 14" you would send me "74 65 73 74 20 31 30 30 20 31 34". (the last two bytes could be blank because that would be the parameter) And that is what's sent over RS232.
We’ve received your message, and we apologize for any inconvenience this may have caused. We’ve updated the product manual and added an example of HEX mode on Page 5 (command in HEX mode: 7465737420313030203134). Please check out the latest version of the manual (https://wiki...anual-EN.pdf)
Hope this helps you! We look forward to your feedback.
Is there a serial command that doesn't set any settings but instead queries information from the board. (like a list of settings or an identification string) Figure 5 makes it seem like the command "test 2" will result in a list of settings.
Hi there! Sorry, but "test 2" isn’t a valid command. Figure 5 mainly shows serial port setup parameters—"test 2" is extra info we’ll remove in future document updates to avoid confusion. Thanks so much for letting us know!
About your question: The board automatically prints HDMI data every second. We just want to make sure we understand your needs clearly—could you share what specific info you’re trying to query from the board, or what function/operation you’re looking to achieve?
I looked at pages 5 and 6 and sent the commands exactly as they are described and got no response from the unit. Figure 5 is in Chinese so that doesn't help. What encoding is used, ASCII?
For quicker and more in-depth technical & after-sales support, we suggest contacting us directly via email at support@geekworm.com.
To help us assist you promptly, please include in your email:
Your order number and the platform where you purchased it.
Your device specs (model, OS, etc.).
The setup/configuration you're attempting, along with your installation and connection details.
Specifics about the issue you're facing—photos or videos are extremely helpful!
Please note that as a highly DIY product, its performance can be influenced by many factors (serial port encoding being just one example). The issue may not be with the board itself. Without sufficient details, it's too early to conclude they're "dead boards."
Send us an email, and our team will provide you with thorough technical support. Even if it turns out to be a product quality issue, we have a solid after-sales solution—so please don't worry!
