New WiPy 3 not broadcasting SSID

[ghost_cheeks]

I soldered and plugged in a new WiPy 3 to an expansion board, then updated the firmware. I can access the REPL via serial (windows 10), but it's not broadcasting an SSID. Is there a quick way to check the WLAN settings over serial?

@ghost_cheeks The problem is caused by the Pybytes variant of the actual firmware 1.20.1.r1, which changes this documented behavior. You can change that by either:

• installing the legacy firmware, which is a slightly older version 1.20.0.rc13.
• creating a file on the WiPy with the name pybytes_config.json and the content:

{"pybytes_autostart": false}

• Using one of the firmware packages provided by @andreas on this web site: https://packages.hiveeyes.org/hiveeyes/foss/pycom. These all do not include pybytes and behave as documented.

@robert-hh awesome! Thanks, I'll give it a shot.

Hi Robert, I have the same issue as @ghost_cheeks that my WiPy3 is not broadcasting SSID. The explanation that you provided last year seems sensible to me that it's the firmware that could have caused it.

I have to first say that I'm a newbie to all these, and might need you to hold my hand through this a little.

First of all, how do I downgrade the firmware to 1.20.0.rc3 (which is in targ.gz format) for the WiPy? And how do I create a file on the WiPy as you've suggested?

Your help will be very much appreciated!

@joshwantstoknow You can use:

import pycom
pycom.pybytes_on_boot(False)

to disable pybytes. Just type these two lines at the REPL prompt. The change is permanent until you change it back and survives power cycles.

Thanks so much @robert-hh , that solves my problem!
