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 #bluenrg-pairing #android #android #bluenrg-pairing

Hi Nick,

I have the same problem as you desctibed, did you find any solution to pair your android device to the bluenrg ? Thanks,MBR

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,cod

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
