Sorry about that! I need to get better at searching on this forum or doing so when I've had more sleep! I took a snippet of the Arduino receiver code from the post you mentioned and I think I'm on the right track now.
Thank you,

micropython NRF24L01 compatibility with Arduino NRFlite/NRF24L01?
Hi! I have just started playing with the NRL24L01 radios and would like to use them for battery powered sensors. I had the thought of using the Arduino NRFlite/NRF24L01 on an ATtiny85 talking back to a "hub" running micropython on an ESP8266 or ESP32. I'm running NRlite as a receiver on an 8266: htt...

Re: Self balancing robot
More progress: Instead of "stalling" a wheel to turn, I used the step rate pins on the A4988 to switch between 1/16th and 1/8th step for a burst of speed on one or the other wheel to turn. Still a little awkward with the control being the OSC app on the phone, but seems to be working enough to turn....

Re: Self balancing robot
Thanks for the reply Peter! Since I have had better success with PWM speed control, my next step is to figure out how to make this turn. The method used was to spin the motors at different speeds (which I can't do with PWM which is limited by a single frequency on the ESP32 as far as I can tell). I ...

Re: Self balancing robot
Hi, A little late to the game I guess, but I have been working on a version of this for the ESP32, MPU6050, A4988/Nema steppers and have had some issues with the Timer frequency. Running at 1/16 microstepping, I tried to find the maximum speed the stepper would run using the following Timer: tim.ini...
