I have measured the signal strength with Android apps. It showed Bluetooth Mate Gold has much better strength (-23dBm vs -74dBm). without antenna, it dropped another 10dBm.
@Kevin Y. : i used 2.4GHz Duck Antenna RP-SMA (WRL-00145) recommended below.
@renechawy : I believe u still can use serial port and you can reset the unit or change PIN. let me know if u need more help
Thanks for your reply, Kevin Y. I am trying to connect this bluetooth from my mobile phone. The distance is about 10 to 20 feet roughly (basically to control things from my living room to my room). I intend to use with door closed (out-of-sight) but when I do testing, it won’t work with more than 2m line-of-sight. So, I am puzzled it is due to my mobile phone or the unit.

btw, well done, Hugo. you did a great job. you have been busy answering all questions for it.
comparing Cortex-M3+wifi($30) and breakout board ($20) will make anyone think twice. may b Sparkfun compared it to SD-MMC breakout ($10). So, the price seems reasonable as it add up a few components but I am more tempted to buy 1 more imp instead of breakout board. has anyone tried before without breakout board?
I couldn’t use this unit for more than 1 m of line-of-sight even with recommended antenna. Does it anything wrong with my set up?
Is it possible to connect two of these units like transceiver? How would those paring could be done?

ok..solved. you need to connect all pins of FTDI Basic board and openLog. Not just TX/RX/5V/GND won’t be able to download.
Under this topic
How do I attach a FTDI Basic board to OpenLog for configuring and bootloading?
No public wish lists :(
