I have a Dell Latitude E6410. But, it does not have built in bluetooth. I have a nondescript bluetooth dongle that works on it's whim. I have had to attempt numerous times to connect it make it work. After trying for more than 100 times (both with Windows native stack and Blue Soleiel), I have managed to connect 3 times. On one occasion, with 4 servos, the software locked up and I had to exit. Batteries are new and once when I could get it to connect, I upgraded the firmware to V16.
I hope the EZ-B is good and my USB bluetooth adapter is not good (bought it in 2010). So, I am going to try another dongle.
If you happen to have a Dell Latitude E6410 with Win 7 with USB bluetooth, can you post here the spec of the adapter please.
It is frustrating not being able to connect. I wasted lot of time trying to connect to the lower of the two com ports as mentioned in the tutorial. All three times I could connect was through the first com port.
I wish there is a wifi connector on board in place of the bluetooth. It will help telnet to it directly without having to go through the laptop running all the time.
