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.
Depending on the role and the current state of the local device; pairing cancelation should be made with a call to a specific function. Normally the Nordic stack would reject invalid calls if the device is not in the correct state; therefore it was assumed that it was possible to detect the state from sd errors. Unfortunatelly this is not true with the latest softdevices as some calls succeed even if the device is not in the right state.
To solve that issue cancelation looks at the current state of the device first to select the right function that will trigger the pairing cancellation.
Note: the call to sd_ble_gap_authenticate was missing in the previous algorithm
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.
1. Problems were seen on the LPC54628 as the ADC clock source was too
high
2. Moved the pin configuration to set Analog mode to the end of the
function

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.
