Hello,
Is the GPIO ground connected to the ground in the RJ jack internally in the BGS5T? I would like to be sure that they are connected and that I do not need to connect the GPIO to ground as long as the rest of the system connects to the ground used in the RJ for powering the module.
Thank you.
Hello,
when I was using just GPIO's I didn't need to connect GPIO ground to ground. But when I was using ASC1 I had to connect GPIO ground to the RS232 ground.
Best regards,
Jure
Hello,
They should be connected.
