Original AT traces had several issue:
- Can be overwritten by other traces (printf/mbed-trace)
- No way to know which direction message was going (TX or RX)
- <cr> and <ln> characters were not visible in trace
etc.
This commit addresses those issues using mbed-trace and showing separately
each filehandle write and read.
State machine has retry logic until device is attached to network.
After this CellularContext does the context activation e.g. connect.
There was no retry logic for context activation. Added logic to
CellularContext level so it's available for at and (upcoming)ril layers.
Internal channels use is enabling ADC "internal path" which needs
to be disabled after measurement.
Same applied here for WB family as was done for others in #10143.
Typically the RTC clock is configured by RTC driver itself.
RNG on the other hand is shared with M0+ core and it is expected that
M4 turns it on at boot time.
When doing so, do not disbale GPIO clocks as they may be used by other
drivers !
As a result, debug will be disabled by default, but can be enabled by
either modifying code or selecting MBED debug profile.
Review HSE clock initialization to match with latest CUBE firmware.
Also there is no need to set the full clock tree again after deep sleep exit.
With this change we get a stable deep sleep mode (when allowed by CORDIO stack).
Issue was seen when running BLE_GAP example from
mbed-os-example-ble.
In STM32WB, the M0 core cannot be reset except if the whole target
is reset. So in case of re-initialization of the BLE stack, the
transport layer should not be initialized again. The HCI reset
command will do the job.
Until the CMSIS pack device name is officially deployed.
then we'll the name as can be found in Keil CMSIS pack
<!-- ************************* Device 'STM32WB55RG' ***************************** -->

There is no need to add FIRST attribute to MAPPING_TABLE as the default
ordering is alphabetical order.
With this change, we don't have any warning with MBED2 and the sections
are properly ordered anyway in BLE cases.
In case of mbed2, BLE feature is not built.
As there is a MAPPING_TABLE in BLE feature which is not compiled in case
of mbed2, the linker reported the below error
[ERROR] "C:/Data/Workspace/mbed/BUILD/test/NUCLEO_WB55RG/ARM/MBED_2/
.link_script.sct", line 65 (column 6): Error: L6236E:
No section matches selector - no section to be FIRST/LAST.
Solution is to check whether BLE is enabled.
