When more the two bytes are written, the blcm_link_ctx_get call inside on_write in ble_nus.c fails (does not return). Two byte writes from central succeed but do not raise the BLE_NUS_EVT_RX_DATA event type though with fiddling of \r and \n in two bytes we do get BLE_NUS_EV...

I changed the ble_nus_string_send to ble_nus_data_send and got a problem. If the p_data is long, e.g. 20 byte, it could not be sent out through ble (was ok with ble_nus_string_send in sdk13.0.0). If I reduced the length of the p_data, I had no problem for sending out...
