Back in February of 2021, Jim Bob Hunter sent me his error messages and his code as I requested. I sent him the following suggestion.

James,

You are not using 'printf' but you left in all the odd formatting characters.
Such as in Line 74:
    Serial.print( "%1u.", tfmP.version[ 0]);
"%1u." is an instruction to print the data as a single character of an unsigned integer.
It doesn't make any sense to your compiler.

You should format the data into a string and then print the string.

Bud 

Maybe you have the same problem and maybe the same advice will help you as well. Please let me know.

Replacing all the printf's with Serial.print fixed it!
This doesnt fix the underlying issue tho.

Thank you for your response.
