.. the primary user of which will be the camera, since the framebuffers
must be allocated via esp-idf allocation function and never from the
gc heap.
A board can have a default value, and the value can also be set in the
/.env file using the key CIRCUITPY_RESERVED_PSRAM with the value being
the reserved size in bytes.

* Fixes#6221 - C3 hang on `import wifi`. Enabling the WiFi PHY was
disabling USB. Now boards that use it set CONFIG_ESP_PHY_ENABLE_USB
explicitly.
* Fixes#6655 - Allows pasting into the web serial page. Fixes reading
more than 0xf bytes at a time.
* Fixes#6653 - Fixes web socket encoding of payloads >125 bytes. Can
happen when printing a long string.
* Fixes C3 responsiveness when waiting for key to enter REPL. (It
now correctly stops sleeping.)
* Disables title bar updates when in raw REPL. Related to #6548.
* Adds version to title bar.
1. Run the socket select task at the same priority as CP. This is
needed because it queues up the background work. Without it, CP
needed to sleep to let the lower priority task go.
2. Close the active socket on disconnect. This prevents looping
over a disconnected but not closed socket.
Fixes#6610. Fixes#6613
- Based on espressif/nimble's blecent example code. Confirms that the characteristic is not empty before trying to catalogue its descriptors.
- Running ble_gattc_disc_all_dscs on empty (no length) characteristics fails with the (not-very-informative) BLE_HS_EINVAL error if this check is not performed.
.. this makes reconnecting without a full reset not work.
Because this works on other generations of the esp32 (c2, c3, etc),
apply this behavior only to esp32.
After this change, it's possible to connect multiple times to wifi in
different runs of code.py or the repl after soft rebooting.
Format:
CIRCUITPY_BLE_NAME = My BLE Board
- the length is limited to 31 characters
- for the NRF version it repeatedly truncates the name if it's too long
- the ESP version defaults to "nimble" if the name is too long
Also, change error handling so that the esp-idf error number
is shown in the traceback in the case of an error.
This allows scanning & connecting to work. I didn't try requests yet.
This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)
This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.
The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.

Use this function instead of several individual configuration functions
to configure such things as Baud rate, transfer size, stop bits,
parity...
This function also resets both the RX and TX Hardware Fifo
reset functions are called to setup the hardware.
This lets the BLE stack run through the wait period after a VM run
when it may be waiting for more writes due to an auto-reload.
User BLE functionality will have their events stopped. Scanning and
advertising is also stopped.
The ``reset`` and ``read`` pins should be optional, but the espressif
code had several places where it assumed they are not, and a bug that
caused a crash on ``release_displays`` if they were made optional.
The bug was caused by the fields for storing pin numbers being set
to ``NO_PIN``, which has value of -1, while the fields have type
``uint8_t``. That set the actual value to 255, and a subsequent
comparison to ``NO_PIN`` returned false.
This allows board code to override the default pull up reset state.
It is useful for pins that are already externally connected, pulled
or otherwise used by the board.
Fixes#5931
