  @foofera I don't know if you ever progressed this issue, but I suggest you try adding a 100us delay between API calls to the PPS library.

  I suggest this because I've found the example code unreliable with a core2, with periodic lockups showing Nack errors on the core2. Very sensitive to host app timing. I think the firmware sometimes goes into error handling and the restart logic is too slow for quick subsequent calls to succeed.

  With stock code, I find the example app hangs after a few seconds to a few minutes. I've tweaked the library to check the gap between the end of one call and the start next, and if under 100us it adds delayMicroseconds() to extend gap to 100us. It now runs for days without issue.

  I think the real fix is to also improve the library error handling with retries, but the delay fix works for my use case.

  @johnericsutton hard to believe that unit is designed in such way to report value only when measured source is above 0...

  I was wondering, I have set up the C6L as a Meshtastic client. Works great. Now i want to use G4 and G5 as Serial ports. In the settings of the Mestastic App you can select them. However, i have not been able to setup a serial connection despite different scenarios i tried. With other Mestatstic device i am able to establish a serial connection.
  Now my specific question is : does anyone know if G4 and G5 are actually used in the Mestastic software. I just cant find anything?
  Thanks

  Hello @Wambo6000

  maybe you are hearing what's described on the product page here: "Abnormal Device Noise".

  Thanks

  For the Atomic Motion Base in UIFlow2, the motion.get_servo_pulse() and motion.write_servo_pulse() functions are available. The pulse width range is currently limited to 500~2500 microseconds.
  I would like to request support for setting pulse values outside of this range. The reason is that there are dual-mode servos on the market where:

  The 500~2500 range controls the standard angular position
  The 3000~5000 range configures continuous rotation speed

  Are there any recommendations or workarounds for using these specialized dual-mode servos with the Atomic Motion Base?

  Hello, I have a standard Echo Atom with the Home Assistant firmware. I’d like to mount this on the Echo Pyramid, but the Pyramid’s instructions only show an example for the S3 Atom. Unfortunately, the setup isn’t working in ESP Home—the GPIO and PSRAM settings don’t match. I just want to use the audio through the Echo Pyramid. A firmware in M5Burner flashe the Atom so that it becomes a Bluetooth speaker, which doesn't help me. But it seems to be compatible. Does anyone have the correct code?
