After updating the SPWF04SA Wi-Fi Module firmware (as per http://docs.ghielectronics.com/hardware/components/spwf04sa.html) and running @John_Brochue’s sample WiFi.cs (https://gist.github.com/Arke64/d5439537c76ba67bd28609f31ada4572) I get the following:
WIND: ConfigurationFailure 10 WIND: PowerOn 171117-0328fe3-SPWF04S WIND: Copyright SPWF04SA WIND: FactoryReset 1 WIND: WatchdogRunning 20 WIND: ConsoleActive WIND: WiFiHardwareStarted WIND: WiFiScanning WIND: WiFiScan 00 WIND: WiFiScanning WIND: WiFiScan 00 WIND: WiFiScanning WIND: WiFiScan 00
I cannot find any information on “WIND: ConfigurationFailure 10” other than the ST user manual’s (UM2114) description:
(Does not Halt) Shown when HW pull-up resistor has no match with enabled interface
Does anyone know what this maybe indicating? I assume because it doesn’t Halt that it is not overly critical. Could it be a residual “error” because GPIO(9) is pulled high but the firmware was updated with the UART interface?
