The gpsmodul is from Navspark and the output is not equal NMEA . Sample: $GNRMC but not $RMC. The libraries TinyGPS++ and TinyGPS can not work with the output.

@ajb2k3 I have updated with the very latest version of the burner which fixes some bugs. Please let me know if it works for you or not.

I'm not seeing that folder. Try WebServer.h I'm trying to modify the arducam to work with the M5cam but having issues.

こんにちは。@lukasmaximus 回答してくれてありがとうございます。 M5GOは購入したときのファームウェアを使用しました。 あなたが教えてくれた日本語マニュアルを使って、UIFlowでの動作は確認できました。 M5GOのWebIDEは古くて使えないことを知らなかったです。 今後はUIFlowかM5Cloudを使います。 ありがとうございました。 Hello. @lukasmaximus Thank you for answering. I used the firmware when I purchased M5GO. By using the Japanese manual that you taught, I was able to check the operation in UIFlow. I did not know that M5GO WebIDE can not be used. I will use UIFlow or M5Cloud in the future. Thank you very much.

I was just about to suggest you update Arduino but you already figured it out. Any other issues you bump into let us know

Hi roadfox, The coding platforms you can connect to (m5go, m5cloud, ui flow) depend on what firmware you have burned on your device. For example if you have m5go firmware you cannot connect to the ui flow site with it. The firmware can be easily changed/re-flashed by using the burner tools on our website for windows http://flow.m5stack.com/download/M5Burner-flow-only.zip for mac http://flow.m5stack.com/download/M5Burner_MacOS.zip You can follow this youtube guide on how to flash your device if you get stuck https://www.youtube.com/watch?v=oEiFLsukAEE Hope this helps, let us know if you manage to get setup

@ajb2k3 Hey, Thank you

@skelstar Hello Please contact with this email, it will help you contact HW engineer of M5Stack tech@m5stack.com

Author of the aforementioned thread here. The hardware mod is the only solution for complete silence - the amplifier inputs will always pick up noise from something. If you look at commercial DAC + amplifier ICs, they also mute the amplifier after a period of silence so it's a common issue.

Hi Now I'm trying the example code of GSM.h to set up a web server. https://www.arduino.cc/en/Tutorial/GSMExamplesWebServer It output a lot of error [image: 1539590014039-01fe194e-2960-4594-a9fe-bacc2bed1fbd-image-resized.png] Anyone knows what happened? thank you

@rop @ajb2k3 I have no idea. So i just force disconnect if the RSSI of the WiFi is too low.

@lukasmaximus Thank you for your comment. I'll see Youtube later.

@watson Hello Watson, I did all you asked and it still doesn't work.[image: 1537997576707-screen-shot-2018-09-26-at-5.20.59-pm.png]. The COM port is open and selected. When I try the hello world sketch I get the following error: A fatal error occurred: Invalid head of packet ('5') A fatal error occurred: Invalid head of packet ('5') Thanks for any help.

Have a try with this link. You can burn the firmware with a easier tool. https://m5stack.readthedocs.io/en/latest/get-started/how_to_burn_firmware_en.html

Here is the article about programming with Arduino IDE For Windows: https://m5stack.readthedocs.io/en/latest/get-started/m5stack_core_get_started_Arduino_Windows.html For MacOS: https://m5stack.readthedocs.io/en/latest/get-started/m5stack_core_get_started_Arduino_MacOS.html

I had the same bizarre issue and I found the solution here ! Just turn the USB C plug around and it works ! Weird.
