Drawbacks to using a pro mini as a serial gateway?
I am planing on using a pro mini as a serial gateway (to connect to my raspberry pi)
I saw in the serial gateway sketch, that it runs on a lower baud rate when run on a pro mini. Does that mean that messages will appear later on raspberry? Are there other drawbacks?
And is it correct that I simply connect rx/TX from the pro mini to tx/rx on the pi and that's it? Plus power and gnd, of course.
@kiesel the pro Mini is the same chip as an Arduino nano, so the speed will be the same for both
Thanks. So why the reduced baud rate than? Sorry, this is probably a noob question.
Maybe the clock frequency is different. So 8mhz instead of 16mhz for the nano.
But I remember you can still run at the same baud rate.
I don't think it will make a big difference anyway unless your sending lots of data.
If the baudrate is 9600, 10 characters will take 10ms to transfer.
Ah, I see there are Nanos with 8mhz and 16mhz, that's why I thought the baud rate of 34800 was specifically for the pro mini.
Do you know whether I just have to hook up TX and rx, power and gnd to the pi or whether I need something else? I am having trouble finding a description of how to do it without USB.
No just the Rx, TX and power should be enough.
