Currently test assumes that 1 sec is long enough to set RTC time and read same time which has been set.
In some cases extra time for synchronisation between clock domains is needed and after setting/reading operations the read value might be different than one which has been set (+1 sec).
Additionally in some cases when lp ticker is based on RTC, the RTC implementation may use mechanism to trace elapsed seconds without modifying RTC registers. In such case it is possible that second will change immediately after setting time.
Add 1 sec tolerance (min possible) for such checks.
In current implementation `rtc_read` function returns number of elapsed us and `rtc_write` function sets RTC time to specified value in us.
Mbed HAL API expects that these functions operate on seconds.
Since lp ticker is also based on RTC provide mechanism to trace elapsed seconds without modifying RTC registers.
The unified NRF51 target and feature BLE directories have been
reorganized to follow the naming and directory structure of the
NRF52 implementation.
This reorganization does not include TARGET_MCU_NRF51822 and
derived targets.
If the frame length is not what we are expecting, it is
found to be a good practise to actually continue with what we
have received rather than aborting. As we have already demodulated
the packet and RX slots are used up, ther is not so much benefit in
dropping that packet.
While configuring RX parameters for the radio, we need to feed in
rx windows 1 and 2 parameters which are computed when we do the transmission.
We are actually setting the physical value of the data rate rather than
data rate table index and the expectation was to set the data rate index.
The asia pacific region supports custom channel planning and
downlink channel request. By virtue of a mistake, this information
was missing and hence a custom channel support was not working.
Fixes issue #6783.
There had been essentially two state machines running in our stack
which was too cumbersome and was not alligned in any symmetry.
In this work we make sure that:
* There are no callbacks from the MAC layer to Stack controller layer.
* Primitives are made local to the mac layer and are presented as
read-only to the stack controller layer.
* Interrupt handling and processing is moved to the stack controller layer.
* Reception is divided into smaller units, seperating handling of Join Accept
and normal data frames. MIC gets its own unit.
* Extraction of data and MAC commands from the payload is also being done now in
its own method.
* To ensure integrity of the stack, and sanctity of the radio payload, we copy the
radio payload buffer immediately in the rx interrupt and hoist a flag that prevents
another interrupt from happening for a short while when we are processing the previous
packet.
* If an automatic uplink is on going, we do not send a TX_DONE event to application
anymore as that is logically incorrect.
* state_controller() is the central engine for the state machine. To save code space and
memory, we are not handling each and every state in the state_controller(). Some of the states
which have no processing to be done, are explicitely set.
* For all the states who need special processing, seperate methods are added.
* Class A always run to completion to IDLE and CLass C always runs to completion as RECEIVING.
Making our LoRaWAN stack thread safe. If RTOS is not present, locks
don't do anything. ScopedLock is used to automate the lock release on
context expiry.
We went through an exercise of adding band information to
any new channel being added. Default channels were looked over.
This commits duly adds missing band information to default channels.
