JTAG needed pins MTDI and MTDO are also strapping pins
Won't using these pins with JTAG interfere with their strapping functions? Per documentation the MTDI controls the flash voltage VDD_SDIO which seems pretty important to not interfere with. Also MTDI is internally pulled-up and MTDO is internally pulled-down. This also seems to potentially cause tro...

gpio_get_level() always returns 0 if pin mode is GPIO_MODE_OUTPUT?
When a pins mode is GPIO_MODE_OUTPUT and you call gpio_set_level(pin, 1), gpio_get_level(pin) always returns 0. Reading a pins value should not require it to be input or input-output mode, correct? I have verified the output pins voltage does go high when set, but gpio_get_level(pin) says it is 0. N...

WiFi can't connect to network with hidden SSID
I am using ESP-IDF v2.1 and Espressif ESP32 Development Board - Developer Edition I am unable to WiFi connect to an AP with hidden SSID. When I change the router to advertise the SSID, then the code works. Is there some option/configuration of the code that allows for this? Note I am not talking abo...

Re: phy: logging randomly emits garbage for timestamp portion
Thank you for quick reply. I am using the SparkFun ESP32 Thing board silicon v 0. I have it properly powered (metered power supply, the uUSB cable and sometimes by battery). I will follow up your hunch on a power issue. I have successfully used these boards for over a dozen other examples/tests (GPI...

phy: logging randomly emits garbage for timestamp portion
The "phy" logging activity randomly (almost always) emits garbage for what appears to be formatting of the time-portion of the reported timestamp.I have the output from the monitor below. This is very problematic since those junk characters often disrupt/stop the output. I am using "screen" as well ...
