Core panic

[crsprsp]

My Board tells me:

SSID name: HelloG............ Connected to network 0C:9E:9D:9B:92:9C 10.10.17.6 IN VINTERTIME Wire ok Could not find a valid BMP280 sensor, check wiring! BH1750 Advanced begin lux 27.50 0 Soil before map: 3523 Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled.

And reboots. Tried with another (new) Board but it's the same.

[pesor]

Are you on 4.3.1

[crsprsp]

Yes, i am. Also downloaded the V4.3.1 again and uploaded it again. Same behavior.

[pesor]

You are getting a division by zero error, It is something in your user settings, I thing

Have you made the BME variable false?

I need your user-variables file, remember to remove your passwords.

check main.cpp for the following

const String rel = "4.3.1"; // Finally the days since last charging works correctly.

// mqtt constants WiFiClient wifiClient; PubSubClient mqttClient(wifiClient);

// Date calculator unsigned long epochTime; String battChargeEpoc; unsigned long epochChargeTime; float battChargeDateDivider = 86400;

The battChargeDateDivider must be 86400

[crsprsp]

ok, here we go:

// // START userdefined data //

include

// Turn logging on/off - turn read logfile on/off, turn delete logfile on/off ---> default is false for all 3, otherwise it can cause battery drainage. const bool logging = false; const bool readLogfile = false; const bool deleteLogfile = false; String readString; // do not change this variable

// Select DHT type on the module - supported are DHT11, DHT12, DHT22 -- Even if you do not have one, you have to uncomment one, as compilation else will fail.

define DHT_TYPE DHT11

//#define DHT_TYPE DHT12 //#define DHT_TYPE DHT22

// Set to true if you have a DHT sensor on the board, and false if not bool dht_found = true;

// Select if 18B20 soil temp sensor available, if available -->> set to true const bool USE_18B20_TEMP_SENSOR = false;

// It is a really good thing to calibrate each unit for soil, first note the number when unit is on the table, the soil number is for zero humidity. Then place the unit up to the electronics into a glass of water, the number now is the 100% humidity. // By doing this you will get the same readout for each unit. Replace the value below for the dry condition, and the 100% humid condition, and you are done.

// Soil defaults - change them to your calibration data int soil_min = 1535; int soil_max = 3300; bool calibrate_soil = false;

// Salt/Fertilizer recommandation break points. You can change these according to your own calibration measurements. int fertil_needed = 200; int fertil_low = 201; int fertil_opt = 251; int fertil_high = 351;

// Give the sensor a plant name, change to true, upload sketch and then revert to false const bool update_plant_name = true; String plant_name = "Tomato";

//If using the Greenhouse automatic watering repo, then assign a waterValveNo to the plant. int plantValveNo = 1;

// define your SSID's, and remember to fill out variable ssidArrNo with the number of your SSID's String ssidArr[] = {"ThisIsMyWireless" }; int ssidArrNo = 1;

const char ssid = ""; // no need to fill in const char password = "My1Passwo4D"; const char* ntpServer = "pool.ntp.org";

// Off-sets for time, and summertime. each hour is 3.600 seconds. const long gmtOffset_sec = 3600;

// Device configuration and name setting const String device_name = "Tgrow_HIGrow"; // Can be changed, but not necessary, as it will give no added value.

define uS_TO_S_FACTOR 1000000ULL //Conversion factor for micro seconds to seconds

define TIME_TO_SLEEP 10800 //Time ESP32 will go to sleep (in seconds)

const char broker[] = "my.broker.com"; int port = 1883; const char mqttuser[] = "ThisUser"; //add eventual mqtt username const char mqttpass[] = "ThisPassword1"; //add eventual mqtt password

[pesor]

I just took a bright new board, and tried to flash the board.

I get exact the same error as you.

Somehow, the current users have used boards with earlier versions of the firmware on them, and then avoid the error.

I will look into it immediately.

[crsprsp]

perfect! glad you could reproduce the error! If you need extended testing, please gimme a sign!

[pesor]

So, I found the reason, and I found a bypass..

Set the bool calibrate_soil = true;

it then writes the file, and you can change to false again, and change again to true, when you do the actual calibration, and then remember to set to false, when calibration has been done.

When the file do not exists, it creates a division by zero error in the program, this is the reason.

I will make a proper fix later.

[pesor]

Thanks, but I know what is wrong, so I just need the time to program the fix.

In the meentime use the worksround in order to use the firmware.
