Rduino 2 with connection problems

hi, I have a problem, I installed a pair of arduino 2 at home with cayenne. however, if I connect it directly to the power supply it does not work. If I connect it to the pc, it starts the listing on the “programming” port and continues to work without problems.
before upgrading to mqtt version 1.1.0 I only had one of arduino 2 and it seemed to work without problems.
can you give me explanations?


I’d check your power supply voltage and make sure you are in the correct range and it doesn’t get loaded down. Just because the power supply is the right voltage on the label doesn’t mean you have enough current to power your devices.

It may have barely functioned on the previous software version, and now there may be more traffic and thus more current needed.
