Arduino Uno - missing serial message

Hi Folks,

I’m having issues with my serial input on my Arduino Uno

the system is receiving serial Data in the form of “REG=PKAAWWW” this is every 3 seconds the reg will change
the system is also receiving Digital input on A3, this is roughly once a second

the problem is that it always received the digital input, but sometimes it misses the serial input.

any help much appreciated

Regards Davon
