(EVK) Firmware update fails over WiFi

[nseidle]

Likely related to #369 .

To replicate:

• Confirm ethernet is not plugged in
• Factory reset
• Turn off Ethernet/WiFi failover (currently TCP menu 7, f)
• Set default network to WiFi (currently TCP menu 7, d)
• Enter WiFi credentials (6)
• Exit menus to save settings
• Update firmware (f, c)

Device fails to even start WiFi. It looks like it's trying to use ethernet.

I'm seeing the same thing when using the Web config on WiFi - in AP mode:

Checking STN mode now...

[PaulZC]

OK. Updating from web config when in STN (WiFi) mode does work. Because WiFi is already up and running when connecting to the SparkFun repo.

otaCheckVersion should be connecting to WiFi if needed - I see wifiConnect in there.

Is the networkGetActiveType perhaps returning the wrong type? It should be returning NETWORK_TYPE_WIFI because we've disabled failover and set the network to WIFI... Is it? Investigating...

[PaulZC]

There's a bug in networkGetActiveType. network is never initialized, making type corrupt. Fix coming...

SparkFun_RTK_Everywhere_Firmware/Firmware/RTK_Everywhere/Network.ino

Lines 485 to 488 in d95eefe

	NETWORK_DATA *network;
	uint8_t type;
	type = network->type;

Resolved by #411

[PaulZC]

This issue isn't fully resolved by #411

With the web config in AP mode:
The firmware version check succeeds, but the firmware update fails with OTA Update: Firmware server not available.

(This requires simultaneous AP and STN. But we know WiFi is capable of that. Investigating...)

[PaulZC]

I found a nasty flaw in wifiConnect. It's been there for quite a while. Embarrassing really... Fixed in #412

[PaulZC]

This is resolved...
