Android application nrf_uart_master connection has closed after 1 sec

[DmitrySol]

I use nrf_uart_master by one side and application realising uart periphireal role on the other side. (It is for debugging. In production Central role will be chip.)

Connection established between phones.

But it is closed after 1 second.

If I press send button in the nrf_uart_master app every second then the connection has remained that time.

The cause is session interval time I suppose. But How can it be fixed?

Hi

Can you check what error code returns when debugging, so we can narrow this issue down somewhat? Could you also please post a link to this nrf_uart_master Android example you're using, as there are many similar examples on GitHub.

Best regards,

Simon
