KW36: Sometimes response not sent for LL_FEATURE_REQ/LL_VERSION_IND

Hi,

I am using KW36 as peripheral, my central is my android app. When i try to pair kw36, sometimes for the "LL_FEATURE_REQ" received from central, peripheral did not send "LL_FEATURE_RESP" and also sometime LL_VERSION_IND is not sent from peripheral.

I have attached airtrace for the both the issues separately.

Please analyze and get back asap.

Thanks.

Regards

Sai Kalyana Raman

Hi Sai,

Sorry for my late reply. COuld you please provide the set up that you have in the KW36?

What is the level of security that you set?

Did you define the NVM?

Mario

Hi mario_castaneda

Level of security - 2

NVM is not defined, but we use EEPROM to save the bonding info.

Also we tried with Vivo X25, we have similar issue that "LL_FEATURE_RESP" was not sent from KW36 for "LL_FEATURE_REQ", i have created a separate ticket (https://community.nxp.com/message/1239606) and attached airtrace in that also, please consider these two tickets as one.

Please get back in case of any further information required.

Hi Sai,

Did you run the example working with the NVM?

Are you sure that you are reading out the bonding information from the EEPROM?

As you description, I am wondering that you device is not getting the correct information from the memory.

Could you please provide more information about your implementation?

Regards,

Mario
