SOLVED: ESP32 esp-now data transfer is pausing
Posted: Thu Apr 02, 2020 3:30 pm
I am working with esp-now. I simply want a nonstop continuous stream of bytes being transferred from one esp32 to another. For my test, I am trying to send a 1 and then a 0, and repeating.
When I monitor the receiver, it appears to receive these bytes as intended, but then pauses for a moment, then continues to receive as intended, then pauses again... repeating.
I put together the code below from snippets of online tutorials.
What can I change in the code to make the stream non-stop? Or should I use a different method than esp-now?
Thank you for your assistance.
