Looking for advice of why we would be getting periodic module failed to respond errors. It will fail for days, then start working again. Works great for hours and then fails again. Is there anything special in the code or wiring for an Uno that we could have missed. Is this a sign of thermal issues? Because it is so sporadic, it is very hard to trouble shoot. We have it wired to relays who then go to a Bareboard to do sounds when a specific rfid tag is found. The whole system has worked beautifully for hours, but then it will crash and burn. Thoughts?
Hi Rouleen,
The “Module Failed to Respond” error usually is the result of a power supply issue. How are you powering the M6E+Arduino? It can also be an issue with an intermittent connection to the Arduino. Can you take a few photos of the top and bottom of your Simultaneous RFID Reader and attach them to your response?
