@zenmanenergy no, you cant do anything. assume that on the one side is a crystal with 12.1mhz and on the other side with 11.9mhz so they are both good for low baud rates and way off for higher baud rates.
no... i set that value in Serial.begin(115200) in the code. I'm talking about the upload speed in the IDE. If I upload the exact same code (it's just outputting hello world to the serial monitor) using an upload speed of 115200, it works. If I set the upload speed to 921600, it looks like it's uploading fine. But the code doesn't seem to run
i just tried some other code that just blinks and LED instead of using hte serial monitor. Same thing. 115200 works, but 921600 doesn't
i'm going to try and reinstall the drivers. maybe that will have an effect
if i have a little more time I'll try and dig through my pile of nodemcus and see if it boils down to specific ones. i tried reinstalling the signed ch340 drivers from sengotta.net, but i'm getting the same as before. It uploads, but only at the 115200 speed.
