It was my mistake.

I did separate nus/uart handler to another file.

But BLE_NUS_DEF(m_nus, NRF_SDH_BLE_TOTAL_LINK_COUNT); was included in both file.

Are you passing m_conn_handle to ble_nus_data_send(), and what is the value does the connection handle have when you get the error?

I am using "nRF Toolbox for BLE" APP from you

My source is from ble_app_uart example.

- Invalid Connection State

Please verify that the android app enabling notifications for this characteristic.
