While following this tutorial:
https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/
I am getting this error when (trying to) uploading the sketch:
esptool.py v2.6
Serial port /dev/cu.usbmodem14101
Connecting....
Chip is ESP32D0WDQ5 (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
MAC: f4:cf:a2:9a:0d:b0
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 460800
Changed.
Configuring flash size...
A fatal error occurred: Invalid head of packet (0xF8)
A fatal error occurred: Invalid head of packet (0xF8)
So it seems like it is connecting in some way, but for some reason the connection gets aborted.
Can anyone point me into the right direction to resolve this issue? Can it be a hardware problem?

I am getting the error below. I pressed the reset button of the esp32 cam but it didn't work. Kindly help.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Because the ESP32-CAM doesn't have a USB port, you must use an FTDI adapter to connect it to your computer to program it. To do this, you must flash it properly.
To flash it properly, first follow this wiring from your FTDI adapter to your ESP32-CAM:
Then upload the code. You should see a message in the Arduino IDE saying that it is compiling. At some point during that process, the FTDI adapter should start flashing, during which you want to press the reset button on the ESP32-CAM.
Once the code has fully uploaded, you need to remove the jumper cable connect the IO pin 0 to GND, and then press the reset button again.
After this, the code should start working and you can disconnect the ESP32-CAM from the FTDI adapter. You need to repeat this process every time you want to upload code onto the ESP32-CAM.
This is a YouTube video of someone demonstrating it in more detail: https://www.youtube.com/watch?v=JYchUapoqzc
Good Luck!
Using the AWS IoT Device SDK from GitHub, I'm testing from my local machine using the basic_discovery.py script I can see that it returns the IP address and port from my Raspberry PI running as a Greengrass device, however, I see that I'm getting invalid return codes from the subsequent request when it is attempting to connect with the PI device. The error messages I am getting are as follows:
Trying core arn:aws:iot:us-east-1:111111111111:thing/GreengrassPI at host 192.168.1.176 port 8883

Any suggestions as to what to check? I did not see anything on this in the troubleshooting guide.
[SOLVED] So what I found was that the device name I was using in the test script was not listed in the client device associations for the Greengrass core device. Adding the association resolved the problem. For anyone else that runs into something similar refer to this for information on associating devices. In summary what happened is that the script was able to look up the Greengrass core device but when it attempted to send an MQTT message to it, the Greengrass core device refused it because the device was not associated to it.
when I try to connect my esp32 card to Thonny IDE for micropython an error is displayed telling me that your port does not exist as a result after some research I was able to install the driver 'CH341SER.EXE' then another error is displayed:
Unable to connect to COM6: port not found
Backend terminated or disconnected. Use 'Stop/Restart' to restart.
by going to device manager I found a new port installed called USB-Enhanced-SERIAL CH9012 (COM6) but it appeared with a yellow label
I tried something else but it didn't work
what will I do in this case?
we are getting ORA-12570: Network Session: Unexpected packet read error from our webapi written in .Net core 2.2. The API is hosted in Alpine Docker OS 3.11 in GCP using kubernetes. We are using Oracle.ManagedDataAccess.Core version 2.19.60.
The intrenal error message we get is
Oracle.ManagedDataAccess.Client.OracleException (0x80004005): ORA-12570: Network Session: Unexpected packet read error ---> OracleInternal.Network.NetworkException (0x80004005): ORA-12570: Network Session: Unexpected packet read error ---> System.Net.Sockets.SocketException (110): Operation timed out.
Per the website http://www.dba-oracle.com/t_ora_12570_tns_packet_reader_failure.htm, ORA-12570 occur due to listener configuration. IS that true? Also Let us know how if tracing works in linux for ODP.Net core.
Thanks
This is a generic error; it is not necessarily related to the Oracle Listener. The key here is "System.Net.Sockets.SocketException (110): Operation timed out." This could be a lot of things; you really need to do Oracle Net tracing to determine what's going on. Could be that your client can't see the network at all, or that network latency or packet routing are not what they should be, or several other things.
I'm programming an app to send SMS through a GSM modem with the serial port. I've been able to send SMS for a couple of days using the MessagingToolkit library but suddennly I'm not being able to send SMS anymore.
According to the logs this is due to a Network error. I found out that the "standard" error that I'm facing is:
CMS ERROR: 512 User abort
I found a list of error codes here http://www.smssolutions.net/tutorials/gsm/gsmerrorcodes/ but I can't find any further explanation on the error.
Does anyone that's familiar with GSM knows what's this error about?
When I'm initializing the modem I also get this error message from the starting configurations, it might be related to the 512 error:
2011.04.11-09.23.16: Sending: AT+COPS=0,2
2011.04.11-09.23.17: Error in command AT+COPS=0,2 : ERROR
Thanks!
Have you verified that you are registered with your operator properly? You can do this by sending a AT+CREG?
Regarding the AT+COPS error message. It seems like you aren't sending enough parameters.
AT+COPS=<mode>,[<format>,<oper>[,<AcT>]]
Are you trying to manually select an operator rather than letting the modem take the default operator setup with the SIM card?
