@gavin67890 [Groan] Bad USB lead out of the packet!
But in case it helps others:
This helped identify the issue:
Serial.printf("Bat Voltage: %dmv\r\n", TimerCAM.Power.getBatteryVoltage());
Serial.printf("Bat Level: %d%%\r\n", TimerCAM.Power.getBatteryLevel());
delay(1000);
I'm having trouble with a Timer Cam F. I am using Arduino and a quite straightforward code with the ENV PRO sensor. Basically, it just logs to Arduino Cloud every 30 seconds.
The thing I don't understand is I'm connected to USB on laptop, everything is fine connects to Wi-Fi logs details, serial mon is okay, etc. I disconnect from laptop and leave connected to a standalone usb power supply and after a period of hours it stops. I hold the reset button, unplug and plug into the USB charger and still no sign of life.
I connect back to the laptop and it starts up again. No reflash, all fine. I disconnected from laptop and plugged back into the charger and it stopped again (straight away this time). What I'm wondering is if, although connected to the USB charger it is running on battery unless connected to the laptop, when it runs on power/charges battery. The charger is definitely okay.
Any thoughts welcome? I just want it to stay on and take power from standalone charger.
Update: Lasted about 2 and a half hours. Then nothing, plugged it into laptop waited for a few minutes and sprung back into life.
Bat Level: 27%
The battery was at 100%. Now charging from laptop and back to 40%. It was connected to an external charger, so why won't it accept charge (only takes from laptop)?
Hi @fbritop,
The unit is just a comms module i.e. it would need a controller like the Atom Lite. In terms of connecting to HiveMQ it could be used to send out MQTT requests. Perhaps you could expand what you are trying to achieve.
If you have many devices (taking to mean sensors) connected to a Atom Lite controller then this could gather readings and send from a single Atom Lite plugged into this module.
If you have many devices (taking to mean Atom Lites) and you want to concentrate to a single mobile access point. It could probably be done by connecting one Atom to a 7080G unit and then relay from other Atom Lites, but a commonly available Mobile Hotspot (e.g. 5G) device to connect all the Atoms via Wi-Fi would probably be better.
The benefit of this device is its low power consumption and design for mobile data at relatively low volumes (see LTE-M and NB-IoT).
As an example, I have a Core2 and IoT base configured to simply request the current CO2 from electricity production once a day and display it. The SIM costs are minimal a few pounds per year, not per month. It is completely standalone, apart from power. For example, I have used it to collect button presses on a micro: bit via serial and relay them to AWS.
Most things M5Stack are split between store. and docs., so see here for the schematic.
I was curious, so I had a look inside my Core2 and it looks like there might even be a convenient breakout port for the SMA connector behind the label.
Yes, mine is the same on the original SPK PAM8303 hat, particularly on startup. I believe there was a mod, and maybe retro, to stop/reduce some of the unwanted noise. I'll see if I can locate the details.
See this page just below schematic. I haven't tried it myself.
The SPK2 is very cheap and maybe better quality also.
I couldn't get it to work with ultrasonic sensors (various other posts with mentions by me). Others have reportedly been ok with Arduino driving it rather than UIFlow. What are you flashing it with, UIFlow, Arduino, etc.?
Cool, thanks, @felmue. I might put the modem on/off on a button instead for a bit more control while testing.
Ha, I was literally working your post. I checked Issues, not Pull Requests on GitHub. I have raised an Issue to second your observation.
I changed mine to:
void iotBaseInit() {
pinMode(IoT_BASE_SIM7080_EN, OUTPUT);
digitalWrite(IoT_BASE_SIM7080_EN, LOW);
delay(5000);
digitalWrite(IoT_BASE_SIM7080_EN, HIGH);
delay(2000);
digitalWrite(IoT_BASE_SIM7080_EN, LOW);
};
I don't get the slow on off blink on the LED, it stays solid. How sensitive are the timings, I noticed your other example below was quite rapid:
digitalWrite(27, 0)
wait_ms(100)
digitalWrite(27, 1)
wait_ms(100)
digitalWrite(27, 0)
wait_ms(100) # GB: Required?
With the value top above a long 5s high pulse the LED held steady from the Arduino upload. The behaviour from the Core2 reset button is odd, I think it turned the modem off, so more fiddling. But IOU a virtual beer!!!
Also, I made a tiny mod to the IoT BASE with a small round file. Now the LED is visible for fault finding.
I have taken the stock example for the IoT BASE and updated it for the Core2. Similarly, it has been modified to remove the MQTT functions, for now, to just allow AT commands for debug. I changed IoT BASE library changed for pin 27 (instead of 12 for the orginal Core).
However, on initial load from Arduino IDE I get the following error message:
E (1659) I2C: i2s_driver_uninstall(2047): I2S port 0 has not installed
The Core2 starts without other issues, begins to connect to the network, etc. However, when I actually checked the wayside I could see that the device was creating and deleting a session about every 7 seconds, wierd. When using the AT commands I could see similar OK---OK, --- , OK---OK, etc. In the IoT BASE there is an LED, hard to see from exterior, so I took the case off. From power up I could see almost exactly the same in hardware from the LED on (about 7 secs), off (about 3 secs), and repeat. I can't find anything in the SIM7080G spec that could do this.
My questions are this:
#1 What is the cause of the error message, is it related, and how to solve?
#2 Is the IoT BASE faulty?
#3 Is there another conflict Core2 vs IoT BASE that this is a symptom of?
#4 Does anyone have a working Core2 IoT BASE example I could try?
#5 Have I missed anything else in my ported example from Core to Core2?

}Hmm, I get that. And appreciate that some of what we are doing here is frontier work, but when breaking changes result in the most obscure error messages know to man it's still a bit painful. The catch to response to repair time is perhaps something the community could work on, with and without GitHub.
I'll cheer up after a nights sleep.
I've still no idea on a fix for the fault posted. Likewise, I have had to swap from M5Core2 to M5Unified for an error earlier this am, so any other thoughts gratefully received.
Update: same Arduino v2.2.1 --> PC fine, macOS the above error [groan], again.
Is anyone else having problems with Arduino upload to device after updates today. I'm able to flash the 2x Core2 with Burner, but if I try anything on Arduino I get this in the serial terminal. Any thoughts how to flash or repair? Or maybe something within IDE has gone wrong.

I adapted what is below from the M5Stack examples for StickC (non-Plus) and ENVII hat to work on an Atom. The only real changes I made were to write out to serial instead of LCD and use the LEDs of the Atom, so it might help you fault find. NB Library and pins need changed to suit your StickC Plus. It's a bit rough and ready, but it certainly worked on ENVII with Atom and StickC.

}@valbuz, This sounds correct.
When you click Download your program is loaded to device and it resets, to run the program.
If you want to try the program click Run for temporary load, a power cycle should clear the temporary program and UIFlow will be available again. Until you are ready to Download, you can just click Run to try your program on the device.
What's your appetite for Arduino like? M5Stack have done an example for the Core2 and ToF sensor. It might give you the control to understand what is happening and correct.
Hi @edpaay,
Perhaps you could widen the description of you setup, I'm sure someone will have some input and be able to help.
AC Measure Module --> Do you mean the AC Measure Unit this or something else (there are other modules related to AC).
ESP32 board, which M5Stack or another manufacturer? Different address to unit (0x42)?
Assuming the AC Measure Unit, connecting over I2C | 3V3 for signal and 5V for power?
For SW environment, Arduino, or something else?
From a fresh Burner flash you would normally get a ping then the UIFlow splash image that persists with menu options. It sounds a bit like it is perhaps booting into an old app. For info, the orange AWS variant works perfectly fine flashed as a stock white Core2. If it goes unresponsive perhaps it's not finishing the flash correctly. You could flash as a white Core2 to confirm it has taken, then flash back to AWS flavour to be sure.
Add line
sht30.init();
straight after Wire.begin(26, 32); // Pins 19, 22 if using Atom-Mate and hats.
For the StickC and ENVII hat example it needs the following change as well.
SHT3X sht30; // Changed from SHT3X sht30(0x44, 1)
Swap the StickC library out for Atom and comment out the LCD lines, it works perfectly as well with the Atom-Lite/Atom-Matrix.
Two lines above need changed in the examples.
Only to have a look through the chip datasheet, see if there's anything else to try.
