Hi,
We have an application which can communicate with a mobile device as a peripheral running on the nrf5340 processor. When a peripheral connection is initially established, we see the peripheral send out an unsolicited LL_PHY_REQ message to the connected mobile device. I have three questions...
1) How do we prevent our peripheral from sending this unsolicited message to the master when the connection is initially made? Is this a controller app (network core) change or BLE host stack (application core) change?
2) It appears that we are not handling the LL_PHY_RSP messages from the master. How do we handle LL_PHY_RSP from the master?
3) How do we change the peripheral to inform the master it only wants to use the 1M PHY in the LL_PHY_REQ message?
Thanks!
