Data loss from bluetooth

I have the same problem like you I send the sensor readings to my pc in three digit format and sometimes they arrive in two-digits. Solving the problem for me wasn't difficult since instead of "054" I get a "540" reading and so all I do is to divide by ten when the first digit is not 0.

BlueSMIRF - RN1 problem

2007-07-03T21:05:50+01:00

Hi,
I run an RN1 connected to my PC via the BlueSMIRF Bluetooth Dongle.
I experience once in a while the problem, that a byte send from RN1 gets stuck. I could wait forever, but the byte is not being transmitted until I send another command which again sends an acknowledgment back to the PC. In this case I receive the previous as well as the new acknowledgment byte.
This happens only sometimes.
I assume the byte gets either stuck on the RN1 serial port buffer or the BlueSMIRF Dongle.
I tried to change the BlueSMIRF to "Fast Mode", but I'm not sure if it really works? I do not receive OK as a response.
Any ideas?
