Without seeing the code, best anyone can do is blind guess. So here's some guesswork... Maybe you need larger receive buffer in Serial1 because your program is spending more CPU time on SPI, so it takes longer before it checks for recently...

Sorry really not much to go on. Things like how you are doing all of the things like sending and reading data? In the main loop? On some form of interrupts, like IntervalTimer? ... Could be as simple as your code is looping doing the SPI and...

Might be a better use of your time to instead create a small but complete program which demonstrates the problem. Many times on this forum we've found problems which often turn out to be subtle programming issues. A diagram or description, or...

Thank you all for your responses. You're right that I need to provide more details. Here's a more comprehensive explanation of my setup: Timing and Measurements: All timing calculations (for sending data and measuring rates) use differences...

Hello, I'm working on a complex project with a Teensy 4.0 and have encountered an interesting issue. Due to business confidentiality, I can't share the full code, but I'll describe the relevant parts and the problem I'm facing. My setup...
