Hello @HappyUser

ESP32P4 has 5 (five) UARTs. See here.

AFAIK all other ESP32 variants only have 3 (three) or less UARTs. (Of which the first one is used for debugging.)

Edit: ESP32S3 devices which have USB-C connected directly to the MCU (e.g. no dedicated USB-Serial chip) can use USB-C to debug (e.g. Serial) and still has 3 (three) UARTs free (e.g. Serial0, Serial1, Serial2).

Please find an example here.

BTW: are you aware of the fact that SIM76XXX is different from what is in IoT Base CatM (SIM7080G) and Atom DTU NBIoT2 (SIM7028)?

SIM76XXX uses LTE (which is different from NBIoT or LTE-M) SIM7080G uses NBIoT or LTE-M SIM7028 uses NBIoT only

Thanks

@felmue said in M5Unit C6L Lora initialisation error:

here

thank you for figuring that out. Honestly, i would have expected that that would be dealt with in M5Unified. Anyway, module works great. Cam right on time on the market because we really need to upgrade our iot devices in the field.

@felmue thanks. Indeed. Leaving out m5unified does the trick. Though I haven’t read anything about an incompatibility between M5Unified and FastLed. Regards.

@easytarget thank you. That is indeed an option. In my experience not to much work to get a Lora module working. We have a number of them in the field. But we would like the tab5 not become thicker as it is. We are now considering to place an Heltec Lora inside. Maybe that could work. Regards.

@felmue Dear Felix,

Actually, we have done nearly the same thing.
We have connected this module: HopeRF RFM95W to the connectors on the back of the Core2. That works great.
We have no idea why the LoRa module does not work with the Core2. Maybe a SPI conflict somewhere deep in the background, maybe a power issue or maybe, and more likely, we are lacking some understanding.
Anyway, we have decided to use a Proto board, solder the LoRa module on it and place that on the backside of the Core2.
We have to do that for 35 devices, but it is fail save.
Thanks for all the effort
Regards

I should note that I am also using the SD card interface and whenever the SD is not detected on power up the display doesn't work either. I believe they are on the same bus.

@HappyUser
I guess it is directly connected to some hardware pin, so it may not be controlled by the user.
Or you can check the schematic and write high and low levels to all LED pins connected to GPIO to try it.

@HappyUser it is not impossible to port the source code from PlatformIO to Arduino or vice versa.
Here is someone who made a script for it.
Maybe the script does not work right out of the box but it could give you some hints or insight about what is needed to port the source code.
As I understand it the two platforms are very similar but their build/make process and their library management are a bit different.

@laursena and @HappyUser

I am also trying to get RFID 2 to work with PaHub and running into similar problems:

How to work with I2C device that requires initiation ahead of time. In this case, it is

MFRC522 mfrc522(0x28);

Why 0x28 show up in CH0 readout while RFID 2 is plugged into CH1 on PaHub.

You mentioned to get an update version of ClosedCub.cpp? I don't have the directory in my library folder, could you please be more specific. (I also googled it but out of luck there as well).

Thanks,

@kuriko
Indeed a strange situation.
It occurs if I use TX=26 and RX=32 and also TX=22 and RX=19 to initiate the can BUS on a M5Atom
ESP32Can.CANInit(); // Init CAN Module. 初始化Can

If i dont initiate WifI I can send data through the CAN BUS. The moment I initiate WiFi, no data come through in the CAN BUS.

I will do some other trials with other devices (M5Core 2 and M5Atom S3) to check if it is a hardware problem.

I do hope to get this solved because if this problem is definite it means the Communication abilites of the CAN bus are limited.
Regards

(* Oh, important : When using WiFi i do receive CAN BUS messages , so that is weird, i really need to dive into this*)

I too have the ATOM_SPK and the sample programs run but create no sound, even with the earphone jack.
https://docs.m5stack.com/en/atom/atom_spk
The PlayRawPCM program runs but no sound.

Also the PlayMP3FromSD is missing files, such as AudioFileSourceSD.h.

Has anyone got these to work?

I can get the beep program here to work
https://github.com/PaulskPt/M5Stack_M5Atom_EchoSPKR

But it seems this program makes a constant hum sounds always, and the beep when button pressed. I assume the battery will die faster too.

ps. What's up with tagging posts as being "OLD" - when it's a year ago, but the programs being tried are 4 years old. It sure seems to me that the "thread" of any issue, even decades old, should still be used to keep that context intact. Oh well..

@felmue said in M5stack GPS, use Serial2 and Serial1:

Well, now i need to recheck what i have been doing.
Your example works both on M5Stick (using ports 0 and 26) and M5Atom (ports 26 and 32).

Thank you, i have some work to do, Ha Ha

@HappyUser is there a way to operate them bot? I'm using it with platformio so maybe is easier to achieve that micropython?

@felmue Thank you. Makes powering some mobile SIM7080 based projects a little easier. We will start some duration tests. Regards

Hello @HappyUser

you are very welcome. I am glad to hear you got it working to your liking. And thank you for reporting back.

Thanks
Felix

Cheers, I'll be interested in your findings!

As you might have seen in this small "saga" here, I have a similar problem with some (but not all) of my 30+ CoreINK devices which have a similar power control circuit.
