Hi everyone,
I have followed every day postings in this forum since November when I bought the EZ-B, but this is my first posting. I have a problem with the controller, it started with firmware update V16 but maybe it was just coincidence. The blue status led is very dim almost off and when I measure the voltage it was only 0.8v. Voltage regulators are giving 5V. Bluetooth led is blinking and I can do the pairing with PC, but I can not establish a connection with ARC. Looks like the PIC controller doesn't start the program. Any suggestion what else I have to check for troubleshooting the problem.
Thanks,
The blue dim would mean the pic partially booted. This could be due to either a loss of power , or the crystal interference. The Stand off mounting holes are close to the crystal, and it's been know to cause this issue. Ensure you are using plastic stands. Also check the screw to make sure it's small enough to not be rubbing. Plastic washers should be used on the screw head side of the pcb.
