Hello,
I’m experiencing recurring issues with the CANFace CF1 “Babel.”
Initially, I used one unit for several weeks with different ESCs (Currawong and Hargrave). Eventually, the device stopped working entirely — my computer no longer recognized it, and it also stopped appearing in the DroneCAN GUI Tool. The only sign of life was the red LED constantly on.
I purchased a second CANFace CF1, but after a few weeks a similar issue appeared. This time, the dongle is recognized by my computer, but it cannot initiate a stable connection to the ESC. Occasionally, I receive telemetry from the ESC, but it disappears after a few seconds.
I have verified that:
- Wiring is correct and unchanged
- CAN bitrate matches on both ends
- Termination and power supply are consistent
At this point, I’m unsure whether this is a hardware failure, configuration issue, or something else. Any guidance would be greatly appreciated.
Thank you for your help.
