Wait, I tried switching it over to serial3, nothing. So I removed the added serial device all together. Nothing. I'm sorry to have bothered you guys. I obviously have something else going on here. Maybe I cooked one of the SPI pins messing about...

Thanks. But that isn't working either. I have pin 7 free and I can move move pin 8's wire to pin 6. This'll leave Serial3 free of anything. I think I'll try that for now. -jim lee

That still seems to get in the way of the SPI port. (That likes to use pins 9 & 10 as chip select) Or maybe I'm doing it wrong? Serial2.setRX(26); Serial2.setTX(31); Serial2.begin(9600); -jim lee

The pinout picture shows Serial2 can be 10 & 9 -or- 26 & 31. How can I select the 26 &31 set as opposed to the 9 & 10 set? Thanks! -jim lee

Thanks! That was exactly what I was looking for! -jim lrr

Does Serial1 hold the program while it's transmitting? It doesn't seem like it does. If not, is there something I can watch to make sure it's all done before adding more? What I'm seeing looks kinda' like I'm interrupting it while it's busy...

There you go. Compiled. run, asked to hold, failed. Now, to be fair. I don't remember this being an issue back when the 3.2 was "the thing". Only in the last few years has this shown up and.. Wait, I just tested this on my laptop Mac. And it...

This is the built in, talking to Arduino IDE serial monitor. The development machine. (2023 Mac)

void setup() { Serial.begin(9600); while (!Serial) {} // wait for Serial printHelp(); } Actually no, this fixes nothing. Exact same result. -jim lee

Thanks! That clears up a lot. One more question, I'm still using up my 3.2s and I'm running into issues that putting text after native Serial.begin(xxx); is either ignored or jumbled up like pieces are being missed while it's trying to get...

If I call.. Serial1.begin(9600); Will it actually run at that slow of a speed? Or will it go to a faster limit? Thanks! -jim lee
