Manual update SDK library, the device can't connect after pairing

[wang_barry]

Hello,

My design board used QN9083.

The project first has created from SDK_2.x_QN908CD 2.2.1 bluetooth_heart_rate_sensor_freertos example. 

In order to update SDK to SDK_2.x_QN908CD 2.2.2,  I replace framework / bluetooth/ libs manually (include lib_ble_5-0_host_peripheral_cm4.a / lib_ble_QN908XC_controller.a / lib_crypto_m4.a) and also enabled pairing and bonding (gAppUseBonding_d  & gAppUsePairing_d). 

After updating SDK, the device can't re-connect after pairing successful.

PS: without updating SDK. the reconnect is successful after pairing successful but enable gAppUseNvm_d not work.

Any step should I do before update SDK?

Hello,

In this case for this type of migration we recommend it to do it the other way around. As there are always improvements in the libraries, there might be also some minor changes or some variables naming conventions that could be affected that the library might be looking for but the current code will not have , so in this case the migration should be made the other way around, it will be needed for you to move your application to the new SDK SW using some example as a base.

Also, please help me verify for the latest version of the SDK in the MCUXpresso Dashboard.

Regards,

Estephania
