Hello,
In my project i am using nrf52840 with my custom board and to upload the code through NRF_CONNECT application with soft device its uploading properly but with segger emmbedded its giving some error like this .please have look and let me know what is the problem.
after this i have add DEBUG in preprocessor definition and i got this
thank you.
Hello simonr,
thanks for your reply,
while debugging i got this after few second

<error> app: End of error report
for more information i copy the error also .
here data_array2 is the data from the sensor board and which is connected to the UART P1.3(TX), UART P1.4(RX) pins of the MCU and at this time BLE is connected to my MCU device but when i am trying to send the data from the customized APP its working for few second and its stopped by displaying the above error and BLE gets disconnected after this.
this is uart_init() for handing the sensor data over MAX232
void uart_event_handle(app_uart_evt_t * p_event)
{
static uint8_t index = 0;
uint32_t err_code;
switch (p_event->evt_type)

(data_array[index - 1] == '\r') ||

if (index > 1)
{
NRF_LOG_DEBUG("Ready to send data over BLE NUS");
NRF_LOG_HEXDUMP_DEBUG(data_array, index);
do
{
uint16_t length = (uint16_t)index;
err_code = ble_nus_data_send(&m_nus, data_array, &length, m_conn_handle);
if ((err_code != NRF_ERROR_INVALID_STATE) &&

}
index = 0;
}
break;

}
this is for handling the ble_uart data
static void nus_data_handler(ble_nus_evt_t * p_evt)
{
uint8_t result[120]={};
if (p_evt->type == BLE_NUS_EVT_RX_DATA)
{
uint32_t err_code;

for (uint32_t i = 0; i < p_evt->params.rx_data.length; i++)
{
result[i]=p_evt->params.rx_data.p_data[i];
NRF_LOG_INFO("result:%s",result);
NRF_LOG_FLUSH();
}
for (uint32_t i = 0; i < p_evt->params.rx_data.length; i++)
{
FINAL[i]=p_evt->params.rx_data.p_data[i];
NRF_LOG_INFO("FINAL:%s",FINAL);
NRF_LOG_FLUSH();
}
if((result[0]=='P') && (result[1]=='R') && (result[2]=='O'))
{
internal_process(result);
}
command_init(result);
}
}
please let me know can i use single UART (P1.3,P1.4 ) for handling this to or i need to use two UART.
from above error i got that when its connected to the ble its fine when data send from the mobile APP its received properly but at the same time data received from the sensor to the RX pin its getting disconnect .
please help me to resolve this .
thank you.
