Avrdude fails programming RFBee V1.1 in Grove XBee Carrier

avrdude: stk500_getsync(): not in sync: resp=0x00

Arduino 1.5.6-r.2 board is Arduino Pro or Pro Mini

Source is RFBee with TM1637 library referenced to set 4 digit display to 1234 in setup

Seems like there is plenty of room:

Sketch uses 11,698 bytes (38%) of program storage space. Maximum is 30,720 bytes.
Global variables use 592 bytes (28%) of dynamic memory, leaving 1,456 bytes for local variables. Maximum is 2,048 bytes.

Any suggestions?

Jumper RFBee DTR to ground.

Board is Arduino Pro or Pro Mini
Processor is ATmega 168(3.3v, 8 MHz)

Jumper RFBee reset to ground while Arduino ide is compiling and for about a second after the IDE switches state to uploading and then remove the jumper.

Simplest solution is to connect .47 uF cap between DTR and Reset

Any ideas why a bluetooth bee will successfully become inquirable but then fail (go nin-inquirable) when attempting to pair a laptop or an android device with it?

Yes, you're right. Auto-program AVR chip via FTDI device, we always add a 100nF cap between DTR and Reset.

Sounds strange, could you show more details how it happened?
