ESP32 Forum

Hi,

I am new to esp32 .

I am trying to do pair between my mobile device and sparkfun esp 32 board.

But i am facing error of incorrect PIN or Passkey.

I had flashed BLE_adv code into esp 32 .ESP32 shows when i turned on my device's bluetoth. but i am facing error when i try to pair from mobile device.


Please help me to solve this issue

Thank you

That's expected, the ESP-IDF doesn't have functions to support BLE pairing yet.

Then how can i pair my mobile device with my esp32 board?

Please help me

Well you can't pair yet - but also for the BLE_adv demo you don't need to, that's just Bluetooth advertisements (in other words broadcasts).

You can set adv_data in the example to the data you want to send, for example:

uint8_t adv_data[31]={0x02,0x01,0x06, 0x1A,0xFF,0x4C,0x00,0x02,0x15,0x71,0x3d,0x00,0x00,0x50,0x3e,0x4c,0x75,0xba,0x94,0x31,0x48,0xf1,0x8d,0x94,0x1e,0x00,0x00,0x00,0x00,0xC5};

will emulate an iBeacon with UUID 713d0000503e4c75ba943148f18d941e major 0 and minor 0. Then you can use an iBeacon scanning app on your phone to detect this.

There are other beacon formats, for example Eddystone.

Don't try to pair, just use nrf connect app or similar

I tried with nrfconnect app but it shows like attached image .

It shows NOTBONDED
It must be bonded ryt?? Then n then my esp32 and mobile device will connect with each other.

facing same issue
I tried as You say.

I just want to connect my mobile device and esp32 board.

if you know than please help me to do that

Thank you

What are you expecting to happen by connecting your phone to the esp32 over Bluetooth LE?

There's nothing running there by default to offer any kind of service, it's just doing exactly what you told it to - broadcast advertising packets - nothing more.

If you want to connect with your phone and se some sample values try the gatt_server example and then use the nRF app.

I am expecting that if esp32 and my mobile device connected means it should be bonded.... as per my knowledge.

so If any notification arrived on mobile i can show on board using led blinking.. for that esp32 and mobiledevice must be connected or i can say bonded.
