Never mind, I see the feature in question was only added in June. I think it's just that the PlatformIO package for ESP32 IoT hasn't caught up yet.

The following statement fails to compile:


wifi_config_t wifi_config = {
.sta = {
.ssid = "TrueSpeedUltra-4YJNX",
.password = "3FKC5R54EFGR",
.threshold.authmode = ESP_WIFI_SCAN_AUTH_MODE_THRESHOLD,
.sae_pwe_h2e = WPA3_SAE_PWE_BOTH
}
};


The compile errors are:


src/main.c:66:14: error ...

I'm using the touch pad peripheral and successfully setting up interrupts with a threshold value determined by reading the touch counter at startup. I'm initialising the peripheral with the following code:


void touch_handler(void*);
...
touch_pad_init();
uint16_t val, average = 0;
const uint16_t ...

Further experimentation suggests that the code above is out by a factor of exactly two. It's not exactly clear why, but it seems that TIMER_BASE_CLK is twice the maximum timer clock frequency.

I'm setting up a timer like this:
timer_config_t tconf;
tconf.alarm_en = false;
tconf.auto_reload = false;
tconf.counter_dir = TIMER_COUNT_UP;
tconf.counter_en = true;
tconf.divider = 1;
timer_init(TIMER_GROUP_1, TIMER_0, &tconf);
timer_set_counter_value(TIMER_GROUP_1, TIMER_0, 0);
timer ...
