I have missed chars when UART sent some data from the on_adv_report() function

Hi!

52832, S132 SDK17.02

When I parsed data in the on_adv_report() function, I want to send some data to UART. Works. But sometimes UART miss some 1 chars. 

What possible reason of it?  May be we should stop scanning? Or it stopped automatically? On the SDK15 we manually stop and star scan from on_adv_report().

Hi,

How do you print the data on UART? Are you using app_uart library together with printf(), or something else? Please post your code for us to understand your setup and possibly be able to reproduce the issue.

Best regards,
Jørgen

Hi!

Sorry for late response.

I used 

ble_nus_chars_received_uart_print()

for send some data to the UART. I meant real UART- not a NUS.

Any idea? First I need to disable scanning when I got and handle one packet.

You could try to enable HW flow control for the UART, to check if the missed chars are due to overflow or similar. You have confirmed that the char is correctly sent from the nRF on the UART interface?
