Change the base time value to more realistic:
START_TIME = 1537789823 # GMT: Monday, 24 September 2018 11:50:23
This fix has been proposed by STM in order to enhance test efficiency.
Current test version did not detect problem with RTC reset on F1 family boards since the base time was too small.
Previously, we weren't filling in RX1 frequecny in rx_window1_config
structure. However, everything worked as in LoRaPHY::rx_config() API
there was a check which filled in correct RX1 frequency.
Now we are filling in RX1 freq. properly while we are computing
parameters for RX1 window.
The idea behind the method post_process_no_reception() is to post
process any outgoing TX but we shouldn't do that if a CONFIRMED message
is outgoing and there are still some retries left.
After transmission we should change the state before invoking opening of
slots as we may start receiving in the rx slots and the state would
suddenly change from SENDING to RECEIVING without going through the
ACK_WAIT state (in case of CONFIRMED messages). Tests show that after
this slight adjustment, our number of ack retries have significantly
reduced.
LinkADRReq mac command can be used by the network server to set a
certain level of QOS using NbTrans field which is applicable to
Unconfirmed traffic only for 1.0.2 spec.
This commit introduces mechanisms to facilitate this QOS. It means to
repeat an outgoing unconfirmed message NbTrans times without changing
its frame counter.
For class C, we have retired the ack_expiry_timer_for_class_c and have
replaced it with another timer which mimics the RX2 closure as in Class
A but doesn't actually close RX2 window. It's just a mechanism by which
the state machine is informed that the you can proceed forward, we have
not received anything in RX2 window either. This is needed as RX2
doesn't timeout in class C (i.e., the radio remains in continuous mode).
In addition to that we need to close any pending timers for Receive
windows after the MIC has passed and the Duplicate counter check has
also been passed.
Before going after an automatic uplink, we should check if there was an
automatic uplink already ongoing, i.e., the ack for the previous
automatic uplink cycle has not been received.
If there is we shouldn't queue the new automatic uplink and wait for
the previous Ack cycle to complete.
Improved the stubs for event queue and nsapi_dns, to allow checking if callback are handled correctly. This involves some memory allocation and deallocation.
The NetworkStackWrapper is not covered as it seems to be deprecated code.
Most functions are empty or simply return "UNSUPPORTED", but it is still worth covering this functions with unit tests to have better control of unwanted changes.
Added more tests, improved the existing ones. setblocking tests were not checking anything, so they were removed and these functions are called in TCPSocket tests instead.
Add functional and line coverage for UDPSocket and TCPSocket. The EventFlagsstub and NetworkStackstub classes are allowed to store multiple return values to allow running internal loops multiple times.
