![]() In this case, we have to make use of a serial terminal like CoolTerm to perform tests on data transmitting and receiving. ![]() This will help us to ensure that everything is working as expected. ![]() Compared to parallel communication (4, 8 or 64-bit), serial communication is popular in embedded systems due to low cost and effective long-distance transmission.įor makers and engineers, we sometimes need to monitor the data that is transmitted between our devices and computer. Serial communication continues to be used all around us today. If you are unfamiliar with serial communication and want to know more, please visit our detailed beginner’s guide – RS232 vs TTL: Beginner Guide to Serial Communication. In contrast, parallel communication sends several bits as a whole, through a few parallel channels. What makes serial communication distinct is that data is sent sequentially one bit at a time through a single channel. What is Serial Communication?Īs you might have guessed, serial communication is used to send and receive data to peripheral devices. This makes CoolTerm a popular and affordable option for users who need a convenient and effective serial terminal software solution. (I don't know where to find this setting, though.CoolTerm is a user-friendly terminal for serial communication with hardware that has been connected to your computer via serial ports.ĬoolTerm is freeware/donationware developed by Roger Meier, and is available for Windows / Mac / Linux devices. Has it anything to do with ASCII and hexadecimal? The first source says to type in ASCII, yet I believe CoolTerm reads in ASCII by default. This forum has had a question about connecting MindWave Mobile to Bluetooth, yet every participant of that thread seems to have gotten past this point of the Bluetooth connection process.ĭoes anyone know what I am doing wrong other than perhaps not retyping the command immediately after it fails the first time? This issue is extremely puzzling, as I know for sure I copied the unique identifier correctly, so there should be no issue. I have yet to see any source on the Internet explain clearly what CoolTerm expects from this command in particular. It also did not work.Įvery single format I tried has failed, yet I know certainly that I copied the unique identifier of the MindWave Mobile 100% correctly. I tried replacing the colons with commas while capitalizing. I tried replacing the colons with commas. I then capitalized while the colons were present. "AOK" was not displayed.) I tried this with capital letters. I could have tried it, though, but I have forgotten since I typed in so many commands that it is difficult to remember.)Īnother source says to type the first four digits, then a comma, then two more digits, then a comma, then the rest of the unique identifier. (Thus, it does me a disfavor to admit that I probably did not try this. Honestly, I perhaps did not do so, so now I expect everyone here to tell me to try that even when there could be another issue. This source ( Hackers in Residence - Hacking MindWave Mobile - SparkFun Learn) says to retype the command if it fails. Since "AOK" was not seen after I typed this command but was seen for previous commands, I conclude that the command has some error. Supposedly, I am to type into CoolTerm "SR,9cb70d90ecc5", and this should cause the terminal to respond with "AOK". Do not worry for me in this respect I shall sacrifice sleep if I must to finish on time.ĭuring this stalling period, I would like to find out why the CoolTerm serial port terminal for Windows will not recognize the unique identifier of the MindWave Mobile EEG headset, which is certainly and exactly "9c:b7:0d:90:ec:c5" on my computer. I accidentally broke the Bluetooth module today trying to factory reset it, so will have to order a new one, thus stalling the project for up to 50% of the remaining time until the due date. I have an Arduino Pro Mini connected to a FTDI SmartBasic connected to a Bluetooth Mate Silver.
