Question

Pairing BlueNRG with Android

I have our BlueNRG device set up to use a fixed pin for pairing.

I am able to successfully pair with Apple iOS decvices and windows phone when I enter the correct PIN when prompted by the device.

However when connecting to an Android device, the pairing always fails even though I enter the correct PIN when prompted. Using a packet sniffer I can see that the reason for failing is 0x04 (The confirm value does not match the calculated compare value).

I have tried with several different Android devices and versions including 4.4, 5.1 & 6.0 and I have the same issue with all of these.

Has anyone successfully paired an Android device with BlueNRG using a PIN code?

Regards

Nick

Hi guys,

I did have issues similar to you guys but I was entering the password as a hex value. Simple I know but may be the cause. I just got mine paired and will work on the comms tomorrow hopefully.

....and as well as that I also noticed that rev6 of the User Manual (UM1686) doesn't provide the parameter details for the 

aci_gap_set_authentication_requirement

comand.

I retrieved theses settings from the rev3 document.

Regards,

aci_gap_set_authentication_requirement

MITM_Mode

= 0x01

OOB_Enable

= 0

OOB_Data

Hi all,

i have successfully paired SPBTLE-RF with Android and iOS devices.

result = self.aci_gap_set_auth_requirement(

            mitm_mode=MITM_PROTECTION_REQUIRED,

            oob_enable=bool(OOB_AUTH_DATA_ABSENT),

            oob_data=b'\x00'*16,

            min_encryption_key_size=MIN_ENCRY_KEY_SIZE,

            max_encryption_key_size=MAX_ENCRY_KEY_SIZE,

            use_fixed_pin=bool(USE_FIXED_PIN_FOR_PAIRING),

            fixed_pin=123456,

            bonding_mode=BONDING)

I have reimplemented  a pure python drivers for

http://www.micropython.org/

 based on bluenrg dk ''2.0.2''. 

MicroPython v1.8.6-114-g8b82429-dirty on 2016-11-30; PYBv1.1 with STM32F405RG
