Installer: simplelink_cc2640r2_sdk_3_10_00_15
Affected example applications: Project Zero (ble5 and BLE-Stack 3), Simple Peripheral(ble5 and BLE-Stack 3), multi_role, simple peripheral oad onchip, simple peripheral oad offchip, simple peripheral secure fw.
Problem description:
If a LL Connection Parameter Request is sent to a peer device that does not supported, LL will not send the packet but return a HCI command status event with the HCI_LE_CONNECTION_UPDATE opCode and LL_STATUS_ERROR_UNSUPPORTED_REMOTE_FEATURE return status.
Steps to reproduce:
1) Program one device with simple peripheral
2) Connect to a BLE master that does not support LL Connection Parameter Request Procedure, e.g. iPhone 7.
3) Form the connection.
If you use a Bluetooth sniffer you will see that no connection parameter update request is being sent. (Neither LL or L2CAP.)
