@martinnn If you build the firmware from the sources you get the most recent version. These numers are in the file pycom_version.h. At the moment it tells 1.18.2.
Revision tags are not added often to the repository. So you see just a few of them.
Last few days: 2 of 6 dead with power only connection, also 2 of 6 dead with USB. So my previous assumption that the crashes are related to the USB cable doesn't hold.
I have to say if this wouldn't be a simple pretty stateless (serial in, MQTT out) sensor application (where I don't mind the sledgehammer approach of an external watchdog reboot), I'd be getting nervous by now and having second thoughts whether these boards were the right choice.
Update: It seems I am getting the crashes only when I have my pysense/wipy connected via USB. I have around 12-15 units running in various setups; those running standalone (battery connection only) seem to do fine, those with USB fail regularly.
@jcaron Yes, and it works!
Now I am trying to figure out where to put my module.
In the ESP8266 version there is a file called ESP8266.ld which contains the list of C files.
Where is the equivalent for ESP32? If there is no equivalent, what shall I look for?
@colateral I believe that the Pycom firmware uses one core for networking and the other to run the actual MicroPython code, or something similar. Not sure how easy it would be to disable one of the cores altogether.
There has been discussion about changing the frequency though, there must be a thread somewhere in the forum with instructions IIRC.
Unfortunately it seems they have moved on and no longer support it. So mobile dev is part of the discussion. Or at least was. I am still hoping they bring it back, as it was exactly what I needed when I decided to "Go pycom".
It seems like the dev team has a lot of good ideas, but jump around between them so much that a lot is never finished before they change course (such as Pylife now being the new path of all effort) and move on. That makes it difficult to really plan a future around a platform that has great promise but divided focus and sometimes short attention span.
And I know that sounds insulting... but I can't figure out another way to explain it. So many other products were offered as "coming soon" or "out of stock, but pre order here" that now seem to be forgotten (sensors, cases, etc) that I am not sure what to build around.
