To create a server with SIM800L, use GPRS to get a dynamic IP from your carrier. Enable TCP listening with AT+CIPSERVER=1,80. Forward incoming data to your M5Stack via serial. Since the IP is dynamic, use a DDNS service or periodically send the IP via SMS/email. Alternatively, have the M5Stack poll a cloud server for commands. SIM800L has limited capabilities, so keep the website simple (raw HTTP requests). Check the SIM800L AT command manual for TCP/IP setup details.

Make sure you're holding the "G0" or "BOOT" button while plugging in the USB or clicking "Burn"—this puts the Cardputer into flash mode. Also try a different USB cable (some are charge-only), and plug directly into your PC (avoid hubs). Lastly, check Device Manager to confirm the COM port is stable and not switching. If all else fails, try flashing with esptool manually via command line.

You have to capture a jpeg from the camera buffer and pass it to the llm... An example could be:

uint8_t* out_jpg = NULL; size_t out_jpg_len = 0; frame2jpg(CoreS3.Camera.fb, 255, &out_jpg, &out_jpg_len); CoreS3.Camera.free(); module_llm.yolo.inferenceAndWaitResult( yolo_work_id, out_jpg, out_jpg_len, [](String& result) { /* do something with result */ .... }, 2000, "ID"); free(out_jpg);

the result will contain:

{"bbox":["195.86","197.75","319.00","280.27"],"class":"keyboard","confidence":"0.69"}

@xhozt try one of oldest firmwares maybe to see if this helps

I second this. I have bought a 6060-PUSH unit and so far have been unable to use it at all. I'm very happy with the M5Stack ecosystem so far but having this currently useless piece of equipment means I am not going to spend any more money on M5Stack equipment if support is this poor.

@flypeek i know that but it still doesn't capture any signals it says that the cc1101 is found but doesn't work idek ????

@felmue What is the IMEI for the device? What other networks has it been tried on?

@ioamas I have an M1 MacBook Pro and I was having issues getting M5Burner to successfully upload applications. M5Burner seemed to find a port but would throw an error during upload.

I eventually found that if I have the Cardputer turned off and hold the Go button down while connecting the USB cable, I was able to successfully upload apps with M5Burner.

I don't know if I have any legacy drivers installed for other microcontroller work I've done, but I didn't have to install any new drivers to get this working. I did find that following the instructions on the UIFlow 2.0 Quick Start page:

"After the Device is turned on, press and hold down the G0 key, insert the USB port, enter the download mode, after connecting, the software will pop up Found New Device."

...didn't work for me, with the only difference apparently that I had my Cardputer turned off when plugging in the USB cable while holding the Go button.

Also, of course, make sure your USB cable is a data cable, not just a power cable.

@ajb2k3 thank you!

@kaidencoolkid No, You need to erase the stick first before burning firmware.

@kaidencoolkid Untill you know how the StickCplus2 works or communicates, only install UIFLow2

@kaidencoolkid Stupid autouncorrect that should have said "my" no "the"!
Yes on my channel.

@SpamerClick
For charging, you just simply plug USB cable into the device
StickCPlus2 dosen't have a power management chip, so there's no way to check power status
