Hi,
I have a few M5StickC's that I didn't touch for a long time(~months), it only works when connected to cable.
What can I do to revive the battery?
Thanks

Hi,
I am using M5StickC and 18650C hat together and encountering a weird issue.
First, when assembling them to each other with the designated screws, it seem to disrupt the on/off button or something because it can't be pressed after wise, and maybe related to the fact that my code suddenly gets stuck for no reason.
This is my code(basically I expected to see led on while it is not in sleep mode):

#include <WiFi.h>
#include <M5StickC.h>
#include "arduino_secrets.h"

char *ssid[] = { SECRET_SSID1 , SECRET_SSID2 , SECRET_SSID3 , SECRET_SSID4 , SECRET_SSID5 };
char *pass[] = { SECRET_PASS1 , SECRET_PASS2 , SECRET_PASS3 , SECRET_PASS4 , SECRET_PASS5 };

//#define TIME_TO_SLEEP_SECONDS 3600
#define TIME_TO_SLEEP_SECONDS 60

const int LED = 10;
int sm;
String deviceID;
bool sentData = false;

void setup() {

M5_Setup();

wifiTask();

}

void loop() {

wifiTask();

M5.update();

getSm();

if(sentData)
{
Serial.println("Going to sleep, good night");
Serial.flush();
delay(3500);
M5.Axp.DeepSleep(SLEEP_SEC(TIME_TO_SLEEP_SECONDS));
}

loopAnalysis();

}

void getSm() {
#define SMPIN 33
float smVal = analogRead(SMPIN);
float smFloat = smVal * 0.01 + (float) sm * 0.99;
sm = (int) smFloat;
}

int httpRequest() {
static WiFiClient client;

Hi,
I couldn't understand from the description of the product, is the grove connection exposed when attaching this hat? or is canceled practically when using it?
Thanks.

@pepsi Both sides don't work

Hi,
Thanks for the reply. Is there a way to reset AXP to its initial values?

Hi,
I have a few M5stickc's that I uploaded the added code, and after uploading it the 5V port stops giving voltage immediatly.
What could be the issue? I am using sleep mode, BLE, and reading some IO's basically.
This is the code:

Hi,
I have a puppyC and can't find anywhere an example for it, or the least where the servos are connected to.
Thanks,
Omri.
