Thanks for the PR. Do you know if this works with earlier versions of the IDF?

Hi David I have tested on 4.4 and 5.1 but nothing earlier.  So, I am not sure.  Its a good question.  Let me know what version you would like tested and I will give it a try Colin ⁣Get BlueMail for Android ​

Hi Colin - thanks for offering, although I think it's better for the code that I advance this (and the other repositories you've submitted PRs to) to target IDF v4.4 or maybe v5.1 anyway.

Anyone using them with older versions of the IDF can continue to do so with the existing code. It's easier to maintain if I keep things moving forward...

When I find the time I'll update my IDF version support statement and merge this PR. Thanks again.
