Basic Firmware which supported same AT commands of XBee modules and make it possible to control such modules via AT.

• ARM Cortex M0

• created in [ Atmel Studio 7 ] 1
• current build created for [ µracoli stack ] 2
• based on IEEE 802.15.4 protocol
• 0.5.x [ repository version ] 3

The AT command version number contains two version numbers at once.

• the first part is the version number of the AT command API
• the second part consists the firmware version on which the AT command API is based

• a bug which prevents to handle received frames was solved
• the firmware version (ATVR) was changed to 0xde10
• the hardware version (ATHV) was changed to 0x0
• consequence: the module can be read by X-CTU Tool only with dresden elektronik add on (not included in GIT folder)
• the UART baud rate works now correctly
• the power level setting is now included
• ATWR updates data only if it has been modified
• several minor bugs are solved

• AT and API mode are running now with state machine parser
• timer to enter and leave AT mode are equal to XBee implementation
• add TX status API frames
• add TX transmit API frames with 64-bit and 16-bit destination address
• add missing RX receive API frames, except RX (Receive) Packet IO
• adding support for broadcast messages
• speed up writing process

• configurable in AT & AP mode (XCTU, HTerm)
• configurable in AT mode PuTTY (other programs are not tested)
• set PAN ID
• set channel
• set destination address (64-bit)
• read own IEEE address 64-bit (ConBee)
• set node identifier
• write parameter to EEPROM
• reset to default
• set the Command Mode Timeout
• stored the symbol to enter the AT command mode
• sending of simple text messages (Point2Point)
• current version support only a package size of 127 bytes, everything else get lost
• sending of remote AT commands (Point2Point)
• received text messages
• received “API Frames” over air, except RX (Receive) Packets
