As such, for improved signal quality and also for safety reasons, we recommend that you use a USB isolator together with your UART to USB adapter: Best regards, The BITalino Team.But for my project I need to be able to communicate with it in realtime in parallel with other measurements and controls of other devices.
![]() I can open it via Matlab (serial() with baudrate 115200), but I do not seem to be able to send anything. Bluetooth Serial Connection Matlab Gui Code In TheI read the code in the python and the c sources, but I do not see anything. Another useful test to try and sort out the problem is to try to send the commands using Hyperterminal or another direct serial access software. If you continue to experience any issues just let us know and well try to help to the best of our abilities. It seems I get two COM ports (why), both with bitalino in their names as can bee seen in the attached picture: I downloaded HTerm and first tried COM5, which did not work. Okay, but I tried COM4 before in Matlab and Matlab throws an error when using fopen on this port. I tried it anyway with HTerm disconnected.: Code: Select all port com4; s serial(port,BaudRate,115200,FlowControl,none); fopen(s); Answer by Matlab: Error using serialfopen (line 72) Open failed: Port: COM4 is not available. Use INSTRFIND to determine if other instrument objects are connected to the requested device. Bluetooth Serial Connection Matlab Gui How To Add TheNot sure if youve done so already, but perhaps the links bellow provide some information on how to add the outgoing COM to Matlab: Do keep us posted on your progress. Does not help a lot in my case, but I thought it could be of interest to other people. ![]() Bluetooth Serial Connection Matlab Gui Bluetooth And AfterThen switch on Bluetooth and after that switch on the BITalino. Then run Code: Select all getAvailableComPort(), which is a function from Matlab Central. Interestingly, when repeating Code: Select all getAvailableComPort() right afterwards, it again shows only COM3, COM5. ![]() Possible reasons are another application is connected to the port or the port does not exist. Now when repeating Code: Select all fopen(s) I get the old error: Error using serialfopen (line 72) Open failed: Port: COM4 is not available. I looked into using a USB connection, but it seems I need to order some additional parts. But I do not quite get what and does not help me much further. You can see a short tutorial on how to connect it here: While using a UART to USB adapter, if you have a sensor such as the ECG EMG EDA connected to you, the signal quality may be degraded. Also, in the unlikely event of a high-voltage power surge (e.g.
