Bulegiga WT12 ============= WT12 is a bluetooth module from Bluegiga. http://www.bluegiga.com/ iWRAP higher layer interface for bluetooth firmware communicate with UART iWRAP HID default setting 115200 8bit/n/1/n TODO ---- KiCAD circuit/PCB design power saving AVR sleep(15ms by watch dog timer) WT12 sleep measuring current consumption measuring battery life of normal usage/idle/intensive usage software reset/bootloarder LED indicator(chaging/paring/connecting) license confirmation of suart.c consumer page is not working authenticate method/SSP SPP keyboard support SPP debug console support mouse wheel feature request to Bluegiga Problems -------- power consumption no consumer page support(bug?) no mouse wheel support no paring management no interactive auth method UART hardware flow control -------------------------- (iWRAP4 User Guide 9.5) Hardware flow control is enabled by default and it should not be disabled unless mandatory, because without the hardware flow control the data transmission may not be reliable. If the hardware flow control is enabled from PS-keys, but no flow control is used, the following steps should be implemented in the hardware design: - CTS pin must be grounded - RTS pin must be left floating Power Saving ------------ power consume without opimization: 4hr to shutdown(310mAh) 2011/08/25: 9hr(310mAh) SNIFF MASTER sleep/WDTO_120MS measure current consumption HHKB keyswitch matrix board idle scanning Bluegiga WT12 module SLEEP command deep sleep on/off in config bits HHKB keyswich how to power off I/O pin configuration when sleeping FET switch for 5V regulator Bluetooth module power off when in USB mode power off by FET switch AVR configuration unused pins ADC SET CONTROL CONFIG ------------------ SET CONTROL CONFIG 4810 SET CONTROL CONFIG LIST SET CONTROL CONFIG 0000 0000 4910 DEEP_SLEEP KLUDGE INTERACTIVE_PIN UART_LATENCY Bit14 UART low latency Bit11 Interactive pairing mode Bit04 Deep sleep Reconnection ------------ SET CONTROL AUTOCALL 1124 5000 HID 1124 HID service class 5000 interval ms HID profile ----------- This is needed to configure only once.
