Issue with the memoryview #135

Open Valadimirovich opened 3 months ago

Valadimirovich commented 3 months ago

I am not sure if it's related to the use of 1.23 firmware, but it happens during the initial connection after the reset

Traceback (most recent call last): File "asyncio/core.py", line 1, in run_until_complete File "", line 448, in outgoing File "mqtt_as.py", line 797, in publish File "mqtt_as.py", line 409, in publish File "mqtt_as.py", line 444, in _publish File "mqtt_as.py", line 235, in _as_write TypeError: object with buffer protocol required

Please can you give me some more detail.

  1. What hardware are you using?
  2. Does the error occur if you run the range.py demo?
Valadimirovich commented 3 months ago

Thank you for your prompt response

  1. ESP32-S3 with SPIRAM, n8r2
  2. Nope, range.py runs fine
peterhinch commented 3 months ago

If range.py runs, publications are occurring successfully, which suggests that the firmware is OK.

The topic and msg args should be bytes or bytearray instances: the traceback suggests that something else is being passed.
