The existing test was expecting that the acknowledgement of the reset command would be the first and only event receive. This assumption is false.
As a consequence, the new code parse all incoming packets and raise a flag in the following circumstances:
* a reset packet has been successfully received.
* RX stream is not synchronized
* The status of the reset command is an error.
Another test has been added that send a serie of reset commands.
Code was written using MBED_CONF_DEFAULT_* but the mbed_lib.json file
that created these values is prefixed with "nsapi" and therefore
final macros are MBED_CONF_NSAPI_DEFAULT_*
The first test focuse on the transport by testing that the reset sequence is
correctly sent to the controller and properly received.
The second test validates that the reset sequence fullfill the right state
of the stack and ensure that bluetooth initialization succeed.
If the automatic uplink is sent directly the call-stack becomes larger than 1K
which may cause serious problems in debug builds. Just to have a respite between
RX and TX we queue an event for the automatic uplink rather than directly undergoing
an automatic uplink.
A peer device that sends a connection parameter update may get block if it doesn't receive a response.
This patch accept the peer request unconditionnally. At some point this event will be managed by the application.
LWIP stack is configured to be 1200 as default. Without debug enabled,
maximum stack size used for asynchronous DNS operations is 880 bytes. With
debug enabled maximum used stack size is 1248. Added configuration
to LWIP to increase stack size by 25 percent when debug is enabled on build.
Currently, if all TX descriptors are in use and IP stack calls K64F/K66F
ethernet driver link out, link out drops the packet. Added 10ms delay
to link out to wait for a descriptor to become available before dropping
the packet.
Changed K64F/K66F power up to return without waiting for link up i.e. for
the ethernet cable to be connected. This is needed for non-blocking use
of driver e.g. for using the driver from event queue.
RX1 and 2 delays needed to be more precise and aggregate tx time was
drifiting because of timing difference between actual tx interrupt and
our processing of that interrupt ever so slightly.
We now take a timestamp of the tx interrupt and take a time diff while
instantiating delay timers. The timestamp is then used to update the aggregate
tx time.
Two new methods are introduced in the LoRaMac class which provide current
timing and current receive slot. These functions are used by LoRaWANStack
for its processing.
