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
- define CIRCUITPY_BUILD_EXTENSIONS to predefined values
- set CIRCUITPY_BUILD_EXTENSIONS in port and board config
- reuse the support matrix "get_settings_from_makefile" to get it
- move the existing port and board specific values
- remove the C3 specific board values because it's not the default
- update build_release_files.py to use get_settings_from_makefile
- 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
rather than setting the heap size statically, micropython allocates
the biggest contiguous chunk possible, but in no event more than half the
total internal sram. On esp32 this gives 123728 bytes of `gc.mem_free`
in the repl.
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.
