Hi,
I am using an NRF52832 on a custom board and I programmed the Broadcast RX code into the board. I use ANTware as the master with a channel period of 4 and send broadcast data which has to be received by the custom board. I use RTT_WriteString to output a string every time a Broadcast is received.
But instead of receiving 4 data packets per second I only receive 1 packet every 2 seconds or so. What could be the reason?
I use SDK 13.1.0. I have also tried this on PCA10040 board with the same results. The code I use is as follows.
void ant_evt_dispatch(ant_evt_t * p_ant_evt)
{
uint32_t err_code;
ANT_MESSAGE * p_message = (ANT_MESSAGE *)p_ant_evt->msg.evt_buffer;
switch (p_ant_evt->event)
{
case EVENT_RX:
if (p_message->ANT_MESSAGE_ucMesgID == MESG_BROADCAST_DATA_ID)
SEGGER_RTT_WriteString(0,"BC\n");
if (p_message->ANT_MESSAGE_ucMesgID == MESG_ACKNOWLEDGED_DATA_ID)
SEGGER_RTT_WriteString(0,"ACK\n");
break;
default:
break;
}
}

uint32_t err_code = sd_app_evt_wait();

}
}
How can I investigate further? Any insights would be appreciated. Thanks.
