What is the maximum clientID length?

[Ryanauger95]

Hi,

We are having small issues connecting with aws IoT with this SDK. When using a clientID that is 21 characters long, we are seeing collisions and getting kicked out even with different clientIDs.

Is there a maximum length? In the code there doesnt seem to be a #defined max size

Thanks!

Hi @PiedPieper,
Client ID max size is defined as 128. You can find the limits for AWS IoT on this link. Please let us know if you have further questions.
