nrf52 unable to sent more than 7 messages

[akok]

I am trying to sent multiple messages from nrf52dk but it seems that i can sent only 7 even if i put a delay between messages . Any suggestions ?

for(int x =0;x < numberofevents;x++){
char str[15];
sprintf(str, "%d %d %d",x,typeofevent[x],events[x]);
uint16_t length = sizeof(str);
err_code = ble_nus_string_send(&m_nus, str, &length);
}

you can use this event to know packet has be transferred ,then sent next packet .
