Sorry, please resume the discussion below.
Seems misunderstood because I gave an ambiguous answer
In addition to BLE, various functions such as WiFi and OTA are implemented and development is underway, so it is difficult to return to WICED 6.4 SDK version ⇒ WICED 6.2 SDK version.
We need to solve the problem that wiced_bt_dev_pass_key_req_reply () cannot be used.
Please advise how to solve the problem of WICED 6.4 SDK version.
Our software team is working on this .
We will update when the fix will be released.
