Why do I use this function bt_conn_le_param_update( ), only after the power on the first time to work, then do not work
Why do I use this function bt_conn_le_param_update( ), only after the power on the first time to work, then do not work
Is there no requirement for the interval between the first call to bt_conn_le_param_update() and the second call?
You cannot initiate a new control procedure whiel another you initiated is actice. Perhaps that is what happened here? If you do, bt_conn_le_param_update() will return an error. I expect this is what happened here.
An error was indeed returned
What does "You cannot initiate a new control procedure whiel another you initiated is actice." mean? I don't really understand
Hi,
The warning is regarding HCI command 0x2013, which is SDC_HCI_OPCODE_CMD_LE_CONN_UPDATE, so that makes sense. I do not seee the full log though nor do I know which parameters you are tryign to udpate to, but it seems the operation is successfull?
Regarding parallell procedures, I means more than one link layer (LL) procedure at one time. That is not allowed per the Bluetooth specification.
