hi,
my GSM-module is Quectel M10 on a GSM-shield.
When I send a SMS containing the letter 'w' the GSM-module always receives "w^", e.g. "with" is received as "w^ith". In upper case it is received correctly "With" .
Is there any setting that the letter 'w' has some special function, and if so, how to change this?
