fixed time interval call send ble_nus_string_send ERROR ???

[Jim_huan]

Hi,guys. 

In my experiment, Firstly,I creat  an app_timer  work every 20ms interval 

APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
err_code = app_timer_create(&m_timer_id,
APP_TIMER_MODE_REPEATED,
TIME_timeout_handler);
APP_ERROR_CHECK(err_code);

and  in the  TIME_timeout_handler,  I send some  string every 20ms that is OK!

But  when I send   ble_nus_string_send   (with 20 bytes)  to my client (nRF connect ) every 20ms in  TIME_timeout_handler  then  the bond  change to disconnect.

I  see the board  led is  always on but disconnect with my phone and  also nothing  ble data  show in the TX Charateristic  ? The board like  dead  and can't work anymore.

How  to  figure this problem  and the can  send  fixed  time  interval   ble data ? Can I need rebuilt  a timer like timer0 ,timer1 or something else but no the app_timer who

base on RTC1?  

I need you help.thanks.
