Weird UART behaviour on esp-hal 1.0.0-beta.0.

[Frostie314159]

Bug description

After upgrading to esp-hal to the beta 1.0 release, the parrot example in FoA, which receives data from parrot.live and outputs it via UART, only the top few lines get output correctly.

To Reproduce

The example in foa can be run with ./run_example.sh parrot esp32 <SSID_OF_OPEN_NETWORK>. You may have to reset the chip a few times, before this works correctly, due to a bug in the Wi-Fi driver. I'll try to create a separate example, later today.

Expected behavior

The complete payload gets TX'ed correctly over UART.

Environment

• Target device: ESP32, ESP32-S2
• Crate name and version: esp-hal 1.0.0-beta.0

write_async doesn't guarantee it will send everything. It returns to you the number of bytes transmitted, and you are expected to handle that.

Oh, ok I didn't know that. It worked as expected on 0.23.1. I should have probably read the docs better. sry.
