- 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.
