Also, I know this is just an example, but perhaps after merging this you might be interested in a PR to move the `FilePicker` from this PR into the main...

@emilk ok, thanks for the response and the link. I'll try and crate a separate example once I've worked out a good way of doing it.

I was able to run the 'access_point' example on a ESP32-WROOM-32 module OK, as follows: ``` $ cargo esp32 --release --example access_point --features=wifi Finished release [optimized + debuginfo] target(s) in...

Hi @JurajSadel can you give details on exactly what board you tested on, and if you have any logs that would be helpful in attempting to figure out why they...

@JurajSadel thanks for the log, i'll diff it to mine and see if there's anything obviously wrong, I also have 2 other boards with S3's on and will test them...

So another board I have here, different design, with a chip from the same batch of MCUs runs the example just fine... ``` $ cargo esp32s3 --release --example access_point --features=wifi...

The 2nd board from the same panel as the first one works just fine, indicating that the power supply circuit must be ok. I use the same components, regulators, caps,...

The issue seems to be intermittent. ``` let timer = esp_hal::timer::TimerGroup::new(peripherals.TIMG1, &clocks, None).timer0; let init = esp_wifi::initialize( esp_wifi::EspWifiInitFor::Wifi, timer, esp_hal::rng::Rng::new(peripherals.RNG), system.radio_clock_control, &clocks, ) .unwrap(); let wifi = peripherals.WIFI; wait_for_button(&mut rwdt);...

When it works, it looks like this - scope zoomed in a bit to show detail. log: ``` INFO - esp-wifi configuration Config { rx_queue_size: 5, tx_queue_size: 3, static_rx_buf_num: 10,...

And here's a log showing that it's intermittent: ``` ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x1 (POWERON),boot:0x29 (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:2 load:0x3fce3818,len:0x16f8 load:0x403c9700,len:0x4 load:0x403c9704,len:0xc00 load:0x403cc700,len:0x2eb0 entry 0x403c9908 I (30) boot: ESP-IDF...
