If your device uses a serial port, CoolTerm should be able to send and receive data messages.Īs you probably hinted, before you can use the app you need to configure the connection by specifying the port number, baud rate, parity and other flow control parameters. This application is designed to help both specialists and enthusiasts who use their computer to control various devices such as GPS receivers and servo controllers. Quick installation, but requires some configuration The program can use the computer serial ports in order to send and receive data. I really appreciate any advice, quite desperate here now.CoolTerm is a compact application that allows you to communicate with various devices by sending messages from a terminal. If you know of other projects around LED's and maybe the raspberry pi 3 I might just forget about this esp8266 for now and get started with the pi first on a more simple project. I had a raspberry pi lying around for almost 2 years now, but I never really had a project which motivated me to get into this stuff. I wanted to build this LED music visualizer as my first project to get in touch with python and arduino thingys. I have the feeling I am missing something else, but afaik I normally just need to plug in the Node via micro-USB to USB into one of the USB-ports of my PC and windows should at least detect any device plugged in. I don't know if my Node is working correctly or if the issue lies on the cables or my PC. I checked every branch for any unidentified devices or anything (even looking at hidden devices enabled) it just wasn't there. But this didn't help at all with my Port problem, thats when I noticed My Node wasn't even showing in my device manager. So I tried to get them shown by looking for Legacyhardware and let windows make them Ports shown in this screenshot. I had no COM-Ports listed in my device manager. Initially I was looking for my COM-Ports, because they were not shown in my arduino IDE ( Port option was greyed out), that's where I noticed the NodeMCU wasn't even recognized by windows. Interestingly, once I tried to reinstall this driver, it said "there is no device found" when deinstalling.Ĭhecking device manager for unidentified devices etc. But the CH340G driver told me it was already pre-installed, which I guess is normal, since windows 10 appearently automatically installs this driver, once I connect the Node to the PC (I didn't had a pop-up or anything though, so I am quite confused about that one). The USB to UART driver installed without problems. I installed them both (even in no driver signature enforcement mode). So I guess the cable works as intended? I tried 4 different cables now, neither works with the Node.Ĭhecking for missing drivers: My initial google troubleshoot told me to check for 2 drivers: The USB to UART and CH340G drivers. The phone gets promptly recognized and I can move files around. Verifying my USB cable works: I used my cell phone cable used for charging and hooked up my Phone to my PC. What I already tried to solve this issue: The blue LED on the board shortly lights up and shuts off permanently, which is normal afaik, so I guess the board works just fine. When hooked up via mini-USB to USB into any of my PC USB 3.0/2.0 ports it won't get recognized by windows 10 (no sound, no pupup, nothing). Today I tried to connect my new NodeMCU to my PC to start on a project I found on the internet. I try to make this as short as possible so here's a tl dr first:
