Photon 2 wifi stability issues on 5.8.2

[gusgonnet]

Hi James, I see the same. I see it going offline then coming online 2 to 5 minutes after, at least sometimes. Other times, it panics, resets and then becomes online.

I also observe the following weird things, for which I need to do more troubleshooting:

• the Photon 2 stops executing user code
• stops printing anything on the serial console
• does not respond to cloud function calls nor cloud variables refreshes

The panic could be related to this, so I need to scan the project in more detail:

Photon 2 does not tolerate Log.info() with a NULL value

Hey, This works fine on Argons and Borons when the variable command is NULL: Log.info("test: %s", command); But it does not work well on Photon 2 (5.8.2 and potentially other deviceOS versions). AI was quick to flag this as a potential red flag: Logging Pointers: Ensure that Log.info can handle NULL pointers gracefully, as logging NULL might cause issues in some logging implementations. Of course, these issues can (and should) be avoided in code, but I realize now that I was relying too …

I appreciate the SPI and I2C fixes on 5.8.2, perhaps we are not out of the woods yet on the stability front.
Of course, it could be that the firmware I am trying to run (which has been running ok for years on Borons and Argons) may still have wrinkles to iron out on the Photon 2. Let's see.
