@redhead-p this should hopefully fix your issue with OSError(114) on Pico W (which uses BTstack).

The test added in this PR is based on your original bug report.

extmod/btstack: Reset pending_value_handle before calling write-done cb.
b4f5998 
The pending_value_handle needs to be freed and reset before calling
mp_bluetooth_gattc_on_read_write_status(), which will call the Python IRQ
handler, which may in turn call back into BTstack to perform an action like
a write.  In that case the pending_value_handle will need to be available
for the write/read/etc to proceed.

Fixes issue micropython#13611.
