Hi,

I'm trying to read the battery level from a Fire controller but even the init code is not working. Is this function not supported for Fire controllers? In the schematic I see that a IP5306 power controller is used in the hardware. So I don't understand why canControl() returns false.

  M5.begin(); 
  M5.Power.begin();
  if (M5.Power.canControl()) {
    Serial.println("Power canControl OK");
  } else {
    Serial.println("Power canControl ERROR");
  }

I'm always getting the ERROR message.

Thanks, Roger

Thanks @teastain, @HWTaro9 but I'm especially looking for pcb footprint data like pad sizes and spacings to start with the pcb design.

Hi,

I want to design a pcb using a M5Stamp Extend I/O Module with SMT assembling. But I could not find mechanical drawings, footprint specifications etc. Do you have a hint for me?

Thanks, Roger

When I use AT+CNMP=48 to disable LTE connections and then check the current IP address using AT+CGPADDR shows no IP (0.0.0.0) but calling AT+HTTPINIT works without an error and after this command I've got a valid IP (see the log below). I will check the device in the field again on the end of this week.

Hi Felix,

I'm using a SIM card from thingsmobile and as far as I understand the APN should always be the same. I've just contacted the thingsmobile support and they did a SIM reset. Sadly I'm now always getting a 4G connection and everything works fine.

I've tried with AT+CNMP=48 to disable LTE connections to further debug but the setting is reset after AT+CRESET and also after a power reset. Although the manuals states: The set value will retain after module reset. I'm able to execute AT+HTTPINIT after changing preferred mode selection but I want to try it after a reset.

Do you have an idea how I can force the SIM7600 to connect using 3G?

Please also see the logs below.

Thanks, Roger

Hi,

Using the AT+HTTPINIT command returns ERROR but I don't know why. The same code worked without problems when I had a 4G connection but now with 3G it doesn't work. Please see the log below:

Hi,

I want to use the COM.LTE module in our camper. We are using LiFePO4 batteries with a maximum charging voltage of 14.6 V.

Is it ok to use the module with an input voltage of about 15 V? The JW5033H step down converter can handle voltages up to 18 V so I think it should be ok? I've tried it also for a short time and it worked.

I'm asking because the m5stack docs are saying: Please strictly follow the input range (5-12V) to prevent damage...

Thanks,
Roger
