Got it. Line 31 in mqtt_as.py seems to effect my connection rate.
_DEFAULT_MS = const(20)

bumping this up to 500 gives closer to 99% successful connection rate.
_DEFAULT_MS = const(500)

Not sure what the downside will be, however.

I am taking Peter Hinche's mqtt_as.py for a test drive. It works like a champ and stays connected for many hours. Trouble is, connections succeed only 1/10 times or so. Mostly I get this: Checking WiFi integrity. Got reliable connection Connecting to broker. mbedtls_ssl_handshake error: -77 Tracebac...

Trying to track down some weirdness implementing umqtt with ssl enabled. I have a simple program to test umqtt and with basic user:password compared to user:password with ssl=True. Without ssl I can publish and subscribe no problem. However, when ssl is enabled, publish works fine but subscribe only...

Good solution - does what I need and reminds me to think outside the box.
Thank you

I am testing various non-default editors with rshell. Nano and Leafpad open edit and save no problem. Geany is giving me some trouble. If I use the --editor geany option when invoking rshell I can edit and save to the temporary file. If an instance of Geany is already open then I am unable to save t...

Success - I can now communicate remotely with my Pyboard and Nextion display (ESP8266 controls communications, as well a few i/o pins on Pyboard including reset). The Pyboard can boot up in one of two ways: Dupterm enabled or UART to UART pass through enabled. # boot.py -- run on boot-up # i/o A15 s...

I have exchanged USB for UART as suggested. I am able to send and receive simple messages - like set display brightness or get buttons pressed. My excitement was short lived however. When I try to upload .tft file things hang very quickly. Output: pi@raspberrypi:~ $ python /home/pi/DAPLC_PY/Screen/n...

Hi, I recently started testing a Nextion TFT display with my pyboard. I am able to send and receive simple instructions through UART(3). A raspberry pi is connected via uos.dupterm(UART(6)) mainly REPL and file transfers. Occasionally new programming -.tft files - need to be uploaded to the display....

Just ran:
>>> import ubinascii
>>> ubinascii.crc32('Test\n')

on Pyboard 1.1:

got:
