Hi i have following questions device: sparkfun thing ESP32 Eclipse oxygen windows 1. i have tested the device by setting the adv interval from 0x06 till 0x19 but the device was not listed on my andriod phone (7.0 Nougat running) application used for BLE named as nRFConnect. what i have configured mi...

Hi all i am working with esp/idf example "gatt_security_server" i have got the feature of pass key which is required to access the BLE device. following are mz questions 1. who is generating this passkey ? sometime it is 5 digit sometime 6 ? can i have my own passkey ? for paring the device ? 2, wha...

Benchmark for microcontroller? I have ESP32 its an IoT device. I have very limited time and i want to flash a benchmark or Algorithm. To get some fruitful results which i can present to PhD level guys. Platform: Linux : IDE : Eclipse Neon

does anyone knows that which harware components are involved in BLE of ESP32 ? i have Devkitc and sparkfun thing board ESP32
i need the exact name of each component which take part in this communication. hardware parts

having this error

make -j8 all
/bin/sh: 1: [[: not found

I got a bench mark from this website https://www.eembc.org/coremark/index.php this is to check the performance of microcontroller the code is available at github https://github.com/eembc/coremark I have a linux 32 bit and eclipse neon does anyone have tried this benchmark or willing to ? does anyone...

in the data sheet its written

''The output of the power amplifier is also adjustable''

how can i do this ? where can i find the option for it ?
i also want to measure the power consumption of Power amplifier/operational amplifier in ESP32

Hi, code: gpio_config_t gpio_conf = { // disable interrupt .intr_type = GPIO_PIN_INTR_DISABLE, //set as output mode .mode = GPIO_MODE_OUTPUT, //bit mask of the pins that you want to set,e.g.GPIO18/19 .pin_bit_mask = (1 << GPIO_OUTPUT), //disable pull-down mode .pull_down_en = 0, //disable pull-up mo...

Hi,
does any one knows how to take out the crystal frequency of ESP32 on GPIO ?
i want to toggle the pin at crystal frequency rate

how can we change the frequency of ESP32 for example there is an option of XTAL crystal frequency 40 MHz and 26MHz. but anyone knows if we can change it using PLL?
