Anyone else having trouble integrating the ted32 module into a Raspberry Pi setup?

I've been trying to get the ted32 board to communicate reliably with my Pi 4 for a small IoT project, but I keep running into intermittent connection drops. The documentation suggests a simple power cycle should fix it, but it seems the issue persists even after multiple resets. I've checked all the wiring and ensured the voltage levels are correct, but the data stream keeps dropping out randomly. Has anyone successfully used this specific module in a similar environment? Any tips on optimizing the power draw or perhaps a specific library I should be using would be greatly appreciated.

Have you checked the ground connection? Sometimes a loose ground can cause random data drops, especially with high-frequency modules.

I had a similar issue with a different sensor module. It turned out the Pi's USB power delivery wasn't enough for both the Pi and the peripheral simultaneously. Try powering the ted32 module from an external, dedicated 5V supply, separate from the Pi's main power bus. This often solves intermittent drops.

Check your baud rate settings. Maybe there's a mismatch somewhere.

Long post, but I found success by implementing a watchdog timer on the Pi side. Instead of just relying on the physical connection, I wrote a small script that periodically pings the module and expects a confirmation packet. If the ping fails three times in a row, it assumes a drop and attempts a soft reset via GPIO. This makes the connection much more robust for continuous IoT monitoring. I also had to use a specific library wrapper that handles the timing overhead, so searching for 'ted32 python wrapper' might help.

Are you using I2C or UART? The communication protocol matters a lot.

Reply to the long post: The watchdog timer idea is brilliant. I hadn't considered software-level heartbeat checks. I'll try implementing that immediately. Thanks!

Did you try a different Raspberry Pi model? Sometimes the specific revision of the Pi's internal power regulation can be the culprit.

Short answer: Power supply. Seriously, use a beefier power bank or dedicated adapter. The Pi 4 can be power hungry, and adding a module often pushes it over the edge.

Reply to the power supply comment: I already upgraded to a 3A official power supply, so I'm pretty sure the main power isn't the issue. It feels more like a data integrity or timing problem.

If you are using Python, look into the `pyserial` library but make sure you are handling the timeouts correctly. Setting an overly aggressive timeout can sometimes cause the script to prematurely assume a drop when it's just a momentary burst of noise.

Have you checked for physical interference? Sometimes nearby RF sources or even bad shielding on the wiring can corrupt the data stream, especially if you are running other high-power components nearby.
