ANCS and nrf8001

[Emp2014]

I used nrf8001 to implement ANCS.It working fine.But when it disconnect for a while and reconnect(reconnect successed).I found Iphone can't send any ANCS message to nrf8001 until turn off/on bluetooth on iphone and reconnect again and it can work fine.

Is it IOS bug or nrf8001 limitation ?

Can you paste message contents of the Pipe Error that you got. If you are using the Arduino SDK , you can turn on the debug printing using the lib_aci_debug_print(true) .

As you suggested .I'm doing the following

void lib_aci_pipe_status_hook(aci_evt_t *p_rcvd_evt_data) { if (lib_aci_is_discovery_finished()) { if (lib_aci_is_pipe_available(PIPE_ANCS_NOTIFICATION_SOURCE_RX)) { lib_aci_close_remote_pipe(PIPE_ANCS_NOTIFICATION_SOURCE_RX); } }

.....

}

But sometime get the pipe error(0x92) when Send the Close Remote Pipe,(The success rate is not 100%).

have you got any idea what am I doing wrong here?
