I meant a design written on paper detailing what you are doing - what's wired to what etc.

sorry for the delay, i had some stuff to study related to the bluetooth, after i studied some example for the simple client and server.vi 

i pass through  the ADVANCE client and server.vi , i got a help from some ppl about it then we got the uploaded vi, my question is when i search on the module i can find it using labVIEW direct but when i want to find the port i get it always COM0, so do i have to use bluesoleil software ?? to set the port  or labVIEW can do this means labVIEW can arrange and synchronize the protocols ?????

and how i can set the port as when it created with the PC????

thanx for your help.....

I toke some time to do a research and i found that i MUST use VISA, and i already had an appointment with a technical guy from NI HQ and he also recommend me to use VISA and leave the BLUETOOTH functions coz he said its low level means we have to open and close and etc etc step by step, i will start to work on it but i am still confusing how is it possible to convert from sting to an ARRAY or string to graph ?????? DO i have to think about the string part and focus on it or i have to study th dynamic data ?????

plz i need help

There are numerous string conversion functions such as Scan From String, Spreadsheet String to Array, etc. Without knowing exactly the string you are receiving, it's impossible to tell what function you need to use. If the string is a single value, then you would use something like Scan From String and wire the value to a chart. A string with multiple values would require a different function.

hi Dennis Knutson 

  i think i have to send a byte which is a single string ???i guess so but if i have to send more as what you said so can be tell me what is the functions that i have to use ???

and do i have to use low level of sting or i can use the high level types???

what is your recommendations  ?? by the way i will post anything i do at least i can have more advice from the ppl in the form

thanx for reply.....

something else plzzzzzzz, i bought a dongle HK-808 and when i check the driver in the control panel i found it there, BUT when i checked the dongle name in the list that supported by labVIEW i didnt find it there.

 by the way i have DELL new model which already have a bluetooth (built in) but that one have to be paired 1st and i have to use a third terminal program which it did not work properly, but when i used the above dongle its working GOOD so the summery will be:

1- dongle can work with bluesoleil 2.6 but the simple server.vi will not work ? ? is that means i have to buy one from the list that i found to make the server.vi run?

2-bluesoleil can work only with the dongle and cant work with the built in bluetooth but the simple server.vi run perfectly with the built in type ?

3- i am using VISA as a virtual serial port  so do i have to be worry about the server.vi or i have to make sure that only parring process is functionally well ??

thanx for any idea

good day to all

finally i found a way to fix my ECG bluetooth application, i replace the data module i have by an audio module

so i will use the acquire sound replaced by the VISA and RS-232 converstion

i test the circuit and the audio module and they are working and i paired the bluetooth with the PC and i got the results

but the signal is not good as it should be i want to filter it using the digital filter of labview to settle this issue

while my ECG cicuit have 2nd order low pass filter at the output and the frequecny for each are 33hz

means its cancel the 50hz or 60hz nois and i hope i can find the guide to filter the signal , i already post the results below

thanx in advance
