KW36: "Connection Failed to establish" error received when trying to connect KW36

[skalyan2]

Hi,

I am using KW36 hid device example with security mode 1 level 2. KW36 is configured as peripheral device and i use it as a advertiser. I am using MCuXpresso KW36 SDK 2.2.2.

I am using just works pairing.

I try to connect KW36 using android phone. 

I have attached snoop log taken in the phone ,From the snoop log, i could see that, there was a connection initiated by the mobile phone at frame 11617, after that HCI_LE_READ_REMOTE_FEATURE was requested, but after this if you see the frame 11645 in the attached snoop log, there i see "connection failed to be established" and a disconnection.

Flashed the below snip for quick reference.

Please say me what are all the possible reason that this can happen and is this something nxp has to fix in controller side ?

Please get back asap as this is critical for my project.

Regards,

Hi XingChang‌,

KW36 we use is in peripheral mode.

LE_Extended_Create_Connection has been initiated from the phone(central) side. We just accept the connection.

Hi Sai,

LE_Extended_Create_Connection should be a Bluetooth 5.0 command, why did you call it?
