Pairing device BLE with android and IOS (IDFGH-14718)

[ElenaG391]

Hi all,

I'm trying to pairing a device with android/IOS. The device sends me a PIN:XXX or PIN:XXXX, the device has a limitation with the number of the digits, it send just 3 or 4digits.
I have to include 000XXX or 00XXXX for pairing, we must have 6digits to connect it.

Could you please let me know how I need to change on the code to accept just 3/4 digits to connect with the bluetooth? is that possible? just we will use the numbers that the device send us: XXX or XXXX. without "0".

is it possible set the 4-digit passkey in ESP-IDF?

thanks
