BLE_HCI_LOCAL_HOST_TERMINATED_CONNECTION

[Kyu]

Hi Nordic!

I am using nRF UART2.0 and nRF51822.

I am sending some data from nRF51822 to nRF UART2.0

But after 3 minutes, I can get disconnection.

and 0x16 error is "BLE_HCI_LOCAL_HOST_TERMINATED_CONNECTION"

Plus) I found that when I connect with android, disconnection occur after 3 minutes,

and when I connect with iOS, disconnection occurs after 90 seconds.

For unlimited connection, what should i change??

Hi

Are you following the guidelines for connection parameters for those platforms? See this document section 3.6 for IOS guidelines.

Update 23.10.2014 According to the above you can select connection interval as low as 20ms, and you can notify up to 6 packets in each connection interval to IOS device v7.1 or later, so you should be able to send up to 50*6=300 packets per second, each packet containing max 20 payload bytes. Perhaps this thread and this thread could provide some further hints on what you need to do.
