Hi @felmue

Ok, than next option would be simbase.com. They offer Sim Cards also for individuals. Prices seem a bit higher... Covererage is given also for Italy.
Anyone has experience with this service?

Thanks, flori

Hello @desmbr

have you checked the boot option? In M5Burner click onto the Configure (yellow) button and then set Boot Option to Show startup menu and network setup. Then click onto Next to set the new boot option.

Thanks
Felix

@ChuckInDallas Yes.

Hi @Kris

From my point of view it should work. Some time ago, I connected the AIN module with a pressure sensor according to this scheme:

Works well in my case.

8883 or 1883 ?

@mohammedalmusimie
have you adapted the codes to CoreS3?

@felmue It looks like I need the binary version of getProtocolString. It seems the following is needed for sending an IRData (the mirror of what was learned from receiving.)

/** * Interprets and sends a IRData structure. * @param aIRSendData The values of protocol, address, command and repeat flag are taken for sending. * @param aNumberOfRepeats Number of repeats to send after the initial data if data is no repeat. * @return 1 if data sent, 0 if no data sent (i.e. for BANG_OLUFSEN, which is currently not supported here) */ size_t IRsend::write(IRData *aIRSendData, int_fast8_t aNumberOfRepeats)

And I need a way to get the IrReceiver to provide the IRData information. So It seems this is in the decodedIRData from the IrReceiver.decode call.

/** * Main class for receiving IR signals */ class IRrecv { public: IRData decodedIRData; // Decoded IR data for the application }

I assume I save these values with the associated functions (volume up, change channel, etc). I see that a lot of those functions are defined for various known operations, but for now I will learn from the IR receiver.

Thanks for the help.

I am using chrome, I will try a cache clear. This applies both to new button blocks and existing in all projects. Any button blocks that had buttons B or C selected have reverted to button A in all of my projects.

Edit: Clearing cache did not work but on another laptop I can see all three buttons, definitely some kind of local issue.

@felmue Thanks Felix. I see now...

for start install M5Burner,
connect your M5StickCP2 via usb to pc/laptop and observe if it will detect com port,
from M5Burner you can then load latest firmware for your device.

@DarshanAtwal As long as you know how to program in micropython You can still use programs like Thonny to program directly.

@kuriko I've checked the link you sent me and adapted it to display an animated GIF. I used the Python script from M5 ( bin2code.py ) to generate a .h file and modified the example from M5GFX ( drawImageData.ino ). It works perfectly!

Thanks a lot!

@DarshanAtwal Use the latest version of UIFlow2 is its just a graphical front ent to Micropython.
There is a console mode in UIFlow2 to directly access the Micropython or you can use a program to directly access Micropython.

@sistar_hh said in Certificate based MQTT (AWS IoT) trouble with changed umqtt:

Hi,
unfortunately the micropython certificate handling for MQTT has been changed last year. good description
Here is the new way to do it:

Create an SSL context context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT) context.verify_mode = ssl.CERT_REQUIRED # Load certificates context.load_verify_locations(cafile='/flash/certificate/ca.der') context.load_cert_chain('/flash/certificate/cert.der', '/flash/certificate/key.der') mqtt = MQTTClient(client_id=client, server=endpoint, port=8883, keepalive=1200, ssl=context) print("Connecting to AWS IoT...") mqtt.connect() print("Done")

While the code and certificates work fine on ESP32-S3 Micropython they result in the following error on uiflow2

Traceback (most recent call last):
File "<stdin>", line 74, in <module>
File "<stdin>", line 52, in mqtt_connect
File "/flash/libs/umqttn/simple.py", line 69, in connect
File "ssl.py", line 1, in wrap_socket
ValueError:
The certificate validity has expired
I triple checked the certificate validity..
Next suspect would be an incorrect system time. Therfore I set the time as follows before attempting to initialize a mqtt connection:

sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)
if sta_if.isconnected():
sta_if.disconnect()
sta_if.connect(wifi_ssid, wifi_password)
while not sta_if.isconnected():
utime.sleep(1)
print("Connecting...")
print("Connected:", sta_if.ifconfig())

print(f"time before NTP settime {time.localtime()}")
ntptime.settime()
print(f"time after NTP settime {time.localtime()}")
import machine
rtc = machine.RTC()

Set manually to a known correct UTC date/time: (year, month, day, weekday, hour, minute, second, microsecond)

rtc.datetime((2025, 3, 14, 1, 14, 0, 0, 0))
print("Manually set time:", machine.RTC().datetime())
Still I get the same error:

Manually set time: (2025, 3, 14, 5, 14, 0, 0, 67)

MQTT Connection failed:

ValueError:

I used the micropython/umqtt.simple/umqtt/simple.py implementation installed as module umqttn in the /flash/libs folder. It differs from the m5stack implementation (which is currently broken for certificate based MQTT due to the described changes in Micropython).

At this point I wonder why the same code (umqtt.simple, demo-code, exactly the same certificate files) work on an UMFeatherS2 MicroPython v1.24.1 but fail on MicroPython v1.24.0-dirty on 2025-03-06; M5STACK CoreS3 with ESP32S3.

I would happy for any hint on how to solve this.

Aha! When trying the following change:
context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.verify_mode = ssl.CERT_OPTIONAL # Instead of CERT_REQUIRED
I successfully connected!

Hello @s1y99

reading your other post, I think you already figured that out yourself. It's not possible to jumper LoRa V1.1 so the same GPIOs are used as it were for the older LoRa module.

Both LoRa modules use the same GPIOs for MOSI (23), MISO (19) and SCK (18). However RST and IRQ cannot be jumpered the same; CS/NSS can be jumpered the same.

LoRa (433 old): RST(26), IRQ (36), CS/NSS (5)
LoRa V1.1: RST(25/13), IRQ (35/34), CS/NSS (0, 15, 12, 5)

Note: GPIO numbers above are for an M5Core (Basic).

Please also see schematics here and here.

Just curious. What is preventing you from modifying your firmware to use the GPIOs of the newer LoRa module?

Thanks
Felix

Hello @peolsolutions

just an FYI: M5Stack Fire doesn't have an AXP192 PMU.

I get the feeling some of your posts are AI generated, no? If I am correct I'd appreciate if you could first verify the technical facts before posting.

Thank you very much for your understanding.

Thanks
Felix

Hello @davekc

M5Stamp-C3: PORT-U pins and USB-C are not the same. Check schematics here.

M5Stamp-C3U: PORT-U pins and USB-C are the same. Check schematics here.

Thanks

if you in uiflow 2 there is "project zone" with lots of users examples, bet there is few with PWM there, with display there is screen rotation block available

stable value? calculated value? - maybe use of internal variable block for calculations

Hello @gadgetguy

I can confirm that enabling RFID prevents M5Dial from connecting to WiFi.

After enabling RFID in M5Dial.begin(cfg, true, true), try M5Dial.Rfid.PCD_AntennaOff() to temporarily disable RFID while using WiFi, then after disconnecting from WiFi enable RFID again with M5Dial.Rfid.PCD_AntennaOn().

Thanks
Felix

@cryptospok
This may be related to the protocol of the SD card itself. You should try SDSQUNC-016G-ZN6MA.
