From my experience i can say it is possible to use ble + wifi + aws IoT in arduino.

OK Thank You so much.

Anyone else have any suggestion are welcome.

Most of 200kB is used by wifi which you do not deinit/free.


I want to use BLE to scan and receive data to send by MQTT through wifi and ble need 90k to init, in total I have 233k heap to use after sketch has loaded in the ESP32.

I'm disconnecting Wifi after sending data to cloud, but it also ...

Hi,
I'm using AWS_IOT library to send data from esp32 to aws cloud server. when I'm creating a object of AWS_IOT to connect subscribe and publish data to cloud it takes lot of heap memory in esp32 so I deleted the object to free up the heap but it just release around 50000 bytes but when created ...

....possibly? But why not just use the existing EEPROM/Preferences library that's based on NVS?

okey
I use spiffs for flash storage and eeprom for nvs EEPROM.

Thank you so much.

ok thank you.

I'm using SPIFFS to store data into flash.
but I was just wanted to know weather we can create EEPROM library or any library so we can perform byte by byte operations in it.

Thank you

Hi,

I'm using ESP32 board with 8mb of flash. I choose this configuration because I wanted to store data in remaining portion of the flash chip. So flash partition I kept is nvs 0x5000 otadata 0x2000 app0 2M app1 2M spiffs 4M.
Here I wanted to store data in permanent memory.

I have main 2 ...

Not sure where you got that path, but from the logs, the partition tool is looking for C:/Users/Akshata/Desktop/esp-idf/examples/get-started/hello_world/partitions.csv .


yes it is working fine with your guide.
Thank you so much.

I am facing one more big issue here when i use esp wifi code to ...

Hi,

Currently I am facing problem to create custom partition in ESP32.
I have created the custom partition settings in munuconfig/partition/custom partition settings and sdkconfig i have saved.
I have created the custom_partition.csv file and kept it in the below path.
C:\Users\Akshata\Desktop\esp ...
