Hello,
I am having strange issue. I'm getting some data from custom service and characteristic. I can see the data being received is correct. However, if I try to pass the data to some other function in another file, the characteristic stops receiving data. Although the mobile app (nRFConnect) shows data saved, but I can not see data being received on the log. Here is the code snippet:
void scr_on_write(ble_ss_t * p_scr_service, ble_evt_t const * p_ble_evt)
{
ble_gatts_evt_write_t const * p_evt_write = &p_ble_evt->evt.gatts_evt.params.write;
if ( (p_evt_write->handle == p_scr_service->char_handles.value_handle))
//&& (p_evt_write->len == 3)) No limit to the number of bytes.
//&& (p_rgb_service->rgb_write_handler != NULL))
{
//p_led_service->led_write_handler(p_ble_evt->evt.gap_evt.conn_handle, p_led_service, p_evt_write->data[0]);
NRF_LOG_INFO("Length of script data: %d", p_evt_write->len);
NRF_LOG_INFO("Script Data starts:");
NRF_LOG_HEXDUMP_INFO(p_evt_write->data, p_evt_write->len);
NRF_LOG_INFO("End of script data.");
// write script data into flash
record_update_scr(p_evt_write->data, p_evt_write->len);
}
else if ( (p_evt_write->handle == p_scr_service->char_handles_1.value_handle)
&& (p_evt_write->len == 1))
{
NRF_LOG_INFO("Script start/stop: %X", p_evt_write->data[0]);
set_script_start_flag(p_evt_write->data[0]);
// save the event and data
scr_evt_write = p_evt_write;
}
}
The set_script_start_flag() function simply saves data into a global variable (within that file). If I comment out this function, everything works fine and I can see data in the log. If un-commented, once I send data to this characteristic, all characteristics in all services stop receiving data.
I have also tried copying p_evt_write globally and later using p_evt_write->data but this also creates problems. What am I missing?
uint8_t global_flag=0;
set_script_start_flag(uint8_t data){
global_flag = data;
}
