Lobo Micropython esp32 wlan frozen

[alien1983]

Hi,
If I have an automatic start wlan esp32 frozen very often during the start. If I run Wlan by manual it is much less common frozen.

The problem only occurs with wifi.

[pythoncoder]

This query should be posted in the Loboris forum where it would be seen by more users of that port (including the author).

[kevinkk525]

I think it could be the common mistake of doing this loop:

Code: Select all

while station.isconnected() == False:
    pass

instead of:

Code: Select all

while station.isconnected() == False:
    time.sleep_ms(50)

[pythoncoder]

If so, this issue is still not fixed.

tl;dr I found it necessary to put arbitrary sleep(t) statements in ESP32 code in a doomed attempt at achieving a resilient MQTT connection. I concluded at the time (August 2017) that the ESP32 port was not yet ready for serious use.

[kevinkk525]

yes it looks like that bug is still present. The wait time is not needed in mqtt anymore though, as using sockets seems to call the underlying RTOS idle methods (or similar) but a busy loop does not. I pinged loboris about that issue on his forum. Should be easy to fix this in his port by having another thread call the needed functions of RTOS (at least that's what I think I have no idea about the underlying code structure)

[alien1983]

I tested this port (lobo) is unstable. It no working good . Ftp telnet webserver . it's easy to hang it.
you have some solution for stable work like ardiuno / raspberry pi .? Esp32 with micropython + ftp telnet/ssh + webserver?

[kevinkk525]

I had not much problems with lobo port. Was stable for me. Just ftp sometimes hangs a bit.
