Hi guys

corresponding github issue for reference.

It seems there isn't an easier way just (yet) than using Espressif Library Builder.

Thanks

Hello @peolsolutions

please stop posting mostly irrelevant information. This topic is about how to remove the magnets - not about what the magnets are good for.

Thanks

Hello @alexcap

according to the schematic, your SW2 setting and the code example I would say that you should be able to receive GNSS data on GPIO16 with baud rate 38400.

Note: I don't have the M5GNSS module to test myself, so my conclusion could be incorrect. I also do not know if the uBlox GNSS module needs to be activated via software commands in any way.

Thanks

Hello @paydogs

my M5PaperS3 running the factory test shows about 4.19 V when fully charged and still on USB-C. When I remove external power it drops to about 4.12 V.

Thanks

Hello @paydogs

I was just about to suggest that from your video it looks like the battery might be flat.

Glad you figured it out.

Thanks

Hello @scroggyg

the added 5 V power switch I use to fully turn the modem off when I want to use M5Tab5 without modem (without the need to de-solder it.

The other modification to control the POWERKEY of the modem via GPIO (instead of the default auto power on) of the modem is required for two cases:

• firstly to restart the modem in case it becomes unresponsive to AT commands and
• secondly to get it out of PSM (power save mode).

Hello @kuriko

thank you for this information. I just retried M5StampPico with UIFlow1 and changed the Start Mode to USB Mode and back to Internet Mode. In both cases I get the blue light. So I guess it's not connected to the server.

Thanks
Felix

Hello @scroggyg

in UIFlow2 under Hardware you can find the Watch Dog Timer (WDT) module.

I created a example in the UIFlow2 Project Zone: M5Tough_Watchdog_Test_UIFlow2.2.8

Thanks

Hello @marnix201

I can confirm there seems to be an issue with UIFlow1 firmware for M5StampPico as I get the same result: solid blue light.

I also tested with M5AtomLite / UIFlow1: same issue - blue light.

However when I use an M5StackCore it connects ok to UIFlow1.

Note: above tested with UIFlow1 firmware 1.14.5

BTW: Any reason you are using UIFlow1? I tried M5StampPico with UIFlow2 and that worked for me.

Thanks

Hello @hacxx

please stop posting incorrect / not very useful information. W5500 is different from ENC28J60 and therefore EthernetENC or UIPEthernet library cannot be used for W5500. Thank you.

Thanks
Felix

Hello @hacxx

please refrain from posting in year old threads which are already resolved. Thank you.

Hello @toffifee

your code works for me using an M5AtomS3 (non R).

That said, M5AtomS3 uses a different IMU chip (MPU68860) than M5AtomS3R (BMI270 / BMM150). So my best guess would be that UIFlow2 is not fully adapted to M5AtomS3R (yet).

@hacxx : FYI @toffifee is using UIFlow2 - there is no Imu.begin().

Thanks
Felix

Hi guys

I now have the LTE-M modem fully integrated into M5Tab5 (including proper external antenna). Info here.

Thanks
Felix

Hello @Boomvalt

I do not have an M5AtomS3R, but with my M5AtomS3 it works for me. See M5AtomS3_PaHUB_EnvIII_EnviV_UIFlow2.2.8 example in UIFlow2 Project Zone.

Make sure you power-cycle everything after changing the I2C address of PaHub. And maybe try another channel for the EnvIII unit?

Thanks
Felix

Hello @Boomvalt

PaHub and ENV III unit share the same I2C address 0x70 by default. See here.

Thanks
Felix

Hello @wrs642

from this and your previous post I would guess that there is no battery connected or it is not charged (enough).

Thanks
Felix

Hello @Schnoble

clever! Maybe you could put your modified version into an Execute mpy code (eg. import)? This block can be found under System.

Thanks
Felix

Hello @Schnoble

you are not doing anything wrong I think. The issue is with UIFlow2 firmware for M5AtomLite. As far as I can tell the default pins are for M5AtomS3 (Lite) and there is one additional pin, which cannot be set from the init block and it is set to a GPIO (8) only available in S3. See here.

BTW: I've created a PR for the issue. So hopefully it will be fixed in a future firmware version.

Thanks
Felix

Hello @smily77

I believe SDIO2 is used so the communication between ESP32P4 (master) and ESP32C6 (slave) can be exclusive, e.g. not shared with other slaves.

Thanks
