I’m work with platformio in the morning and all was ok. 2 (Build #CL-232. In this case, you have to manually select a different serial port to upload code on each microcontroller because, by default, PlatformIO handles port selection automatically. Weirdly it worked one t I upgraded platformio tonight and the expressif sdk, now I can no longer upload to my board unless it’s in boot mode. The monitor is the one you are looking for. If your microcontroller can’t generate a clock for 230400 baud within the tolerances of the UART protocol, you’re gonna get garbage. ini do you have? Which board? It may just be that either the board first starts sending messages at a different baud rate, thus messing up the decoding of the data, or that the serial monitor opens too late (which can be tested by adding a delay(1000); before the Serial. Sets the serial monitor baud rate. But, The PlatformIO Monitor does not work when I upload the same code with the VScode PlatformIO. PlatformIO can not disconnect/connect to a target device automatically when CoolTerm is used Connect to Serial Port of remote device and receive or send data in real time. Match baud on . Select your desired serial port by writing the “upload-port” command (image below). This lesson builds directly on Episode 5: Using PlatformIO and Mayfly. 230400. But when I upload my code from PlatformIO, the serial monitor in both Arduino IDE and PlatformIO starts The “Serial Monitor” section is a VS Code extension. I thought that was the issue as well. What’s the problem with the PlatfomIO’s serial monitor, what do I need to change in the setups? Thanks: T EDIT: It seem’s I have the same problem (just installed PlatformIO on macOS). You can set the baud rate and line ending mode in their own drop down boxes. Hi! Forgive me if this is not the most appropriate board but maybe you can at least direct me further. Additionally, check the quartz on your ESP32 board. begin(), or 115200 (default value for Arduino-ESP32) and you should see all output printed by Serial.

If I use the PlatformIO’s buildt in serial monitor, it only shows NULL’s instead of characters, but if I try it with the same BAUD-rate at Arduino IDE, it works correctly. Navigate to the platformio. 1. I used this to display multiple serial interfaces simultaneously in the video. I thought that slower speeds would work more consistently but Jumped into platformio from visual studio code (VSC). I was getting results identical to what you would see when setting a wrong baud rate. speed field will interfere with the programmer's baud rate. robertcerny March 31, 2023, 11:43am Hello, I am trying to read the output of the serial monitor but the only thing that shows up is the following: Executing task: C:\Users\Dominik. Then, as you have already noted (also in Home · espressif/esptool Wiki · GitHub), GPIO0 has to be connected to GND, then the RESET button needs to be pushed (or RESET connected to GND momentarily). These pins are already used as TX and RX for Serial and are wired to the board's USB/UART chip. The serial monitor setup detects the correct comm port and the baud rate is also set correct. Ctrl+T followed by Ctrl+H Help. I tried a putty terminal using both 9600 and 115200 serial baud When I upload my code from the Arduino IDE, the serial monitor in both Arduino IDE and PlatformIO works perfectly. Fixed code below. If I put a blink into the loop also, it blinks as expected. ini using monitor_speed = 115200. I actuallly tried that before posting. Some boards use a 26 MHz quartz (instead of the more common 40 MHz quartz). exe device monitor < — Available filters and text transformations: colorize, debug, default, direct, esp32_exception_decoder, hexlify, log2file, nocontrol, printable So this issues seems to be a plugin issue. ini and in the code) setting monitor_rts and monitor_dtr to all combinations of 0 and 1 What could be going wrong? [env:nodemcuv2] platform = It just shows the baud rate I set and the USB port. begin, with no effect on the serial monitor. Coming back to this problem (making the baud setting discoverable), an easy solution would be to make all new It doesn’t hurt to check the baud rate in the sketch to make sure it matches your platformio. ini use: monitor_speed instead of monitor_baud. begin(115200); } void loop() { Serial. ini and the code are the same. Open the Arduino IDE and configure the port to suit your board. writing monitor_baud = 115200 in the platformio. The only way to change this is setting a new baud rate by ctrl-T intervention each time I need output test messages. 42, built on September 12, 2023) this morning and it is still there. Ctrl+T Menu. Even manually opening a serial monitor does not work properly. ini to make it work, definitely monitor_port and maybe monitor Hello, On my main computer i programmed my esp32 (with all the other components) as an aquarium controller (turn light, filter, etc on and off manually and using alarms of the ds3231) But when i installed in place, sometimes the alarms are not trigering, so i need to connect it to serial monitor in order to see whats hapenning. Warning! monitor_baud option is deprecated and will be removed in the next release! Please use monitor_speed instead. You can switch between the monitor ports by using monitor_port. Computer: Mac Studio M2 Ultra Board: Xiao ESP32-C3 Platform IO: PlatformIO Core, version 6. You may need to add some of these parameters to platforio. Restarted VSC to pick up baud change. It doesn’t show up as COM-port. Getting back into it after a while I suddenly can’t get any output from the serial monitor. ( I tried in PlatformIO and Arduino 1. 1.
