Backchannel Boards
DHCP Access
user does have access DHCP server DHCP server linked DNS, user must static address.
source available Developer provide users with ability create their HAL-based their hardware requirements. sources have their naming conventions updated keep them either "ember" "em" namespaces. However, most have either "board" "micro" prefix. interface APIs documented Doxygen HTML files provided with this release. bootloader provided loading applications. This bootloader should used protect manufacturing data stored flash tokens. list tokens their associated information token-name.h token-default.h files. separate application note will issued website support.ember.com explaining reset these tokens bootloader overwritten.
Stack APIs
Note: message size within packet variable dependent functionality being used. maximum message size stack bytes. Below table with functionality that will reduce available packet size:

Message Size bytes Subtract bytes Subtract bytes Subtract bytes
Multicast
Avoid logic that cause nodes respond multicast same time this cause excessive network traffic. some delay jitter responses.
emberSetRadioPower()
Invalid power argument will result error status code. stack does round nearest valid setting stated documentation.
emberSetRadioChannel()
Invalid channel argument will result error status code. stack does round nearest valid setting stated documentation.
emberGetSendingTerminal()
Allows applications find which terminal sent current incoming datagram. This only called from emberIncomingMessageHandler().
Serial Re-Initialization
user should call emberSerialWaitSend() before serial reinitialization ensure that transmission complete.
Calling stack APIs when stack asleep
application developer should call stack APIs when stack asleep
Calling Ember routines from within callback routines
Application developers should careful call ember from within callback routines. This cause recursive calls other problems.

Closing stalled connections
application should close connection longer receiving messages some point avoid stale connections. connection could have been closed other side reboot.
Remote node gets failure indication when connection attempt fails
Remote node failure indication when being connected connection fails. Only initiator should this failure message.
3.10 EmberMessageSent() always called after connection closed
When connection closed, stack call emberMessageSent() outstanding messages.
3.11 error code: EMBER_MISSING_EUI64
There error code with value which EMBER_MISSING_EUI64. debug users will "Err over debug port. debug off, assert will occur.
3.12 Link-level security
There currently enable/disable link level security. disabled default. customer enable link level security using token rebooting.
3.13 emberTick()
Avoid doing things that prevent emberTick() from being called length time, especially presence lots network traffic.
Ember Studio
Note: Ember Studio runs using base application running node that acts gateway network. This "gateway" node must have Ember Studio application loaded order run.
Debug Window
Ember Studio contains debugging capabilities assist during development testing applications. following noted debug operations Ember Studio: When under heavy load, debug messages dropped. When connecting node with Ember Studio Debug Reader, will reconfigure baud rate specified debug port debug preferences, however baud rate changed back disconnect.

Release Notes, CC1020/EM2420 Developer Release
When real-time updates displayed Debug Reader, only most recent 1000 messages displayed. 10,000 older messages been viewed disabling real-time updates pressing view button.
Debug Saved Connections Ember Studio
Saved connections stored preferences files Ember Studio directory user's user remove unwanted connections editing deleting preferences file. Note: Ember Studio never selects time server previous disconnected. When using debug reader studio, selects first node connected time server rest clients. However, time server node disconnected, time server never selected.
