CC1352R: Missing data from sensor

Hi,

My setup:

Sensor

• CC1352R custom board
• RSSI -47..-52 (image 2)
• SDK 3.30.0.03

TI 15.4 stack Linux

• 3.30.00.12
• CC1310 Launchpad as coprocessor with SDK 3.20

I´m sending from the sensor a payload of 160 bytes(233 bytes entire packet) for 64 times with a reporting time of 2s after I receive 64 packets I change the reporting time for 30min. Then in TI 15.4 stack I save the packets to a file and I notice In the data I save I miss a few packets of the 64 I send.

In sensor side I have periodic event in sensor.c function Sensor_process() wich is set after reading the sensors in Sensor Controller Studio. The data is acknowledge by the collector(see image 1)

    /*Periodic event*/
    if(Sensor_events & SENSOR_SEND_PERIODIC_EVT)
    {
        /* To set the msg lenght and permissions*/
        scs_IRQ_task = false;
        scs_PERIODIC_task = true;
        /* Read sensors */
        readSensors();
        /* Process Sensor Reading Message Event */
        processSensorMsgEvt();
        /* Clear the event */
        Util_clearEvent(&Sensor_events, SENSOR_SEND_PERIODIC_EVT);
        /* Set clock for next reading */
        Ssf_setReadingClock(configSettings.reportingInterval);
        /* Clear Flag */
        scs_PERIODIC_task = false;
    }

 I save the packets in appclient.js in the function appC_processDeviceDataRxIndMsg(data). I create write stream it takes around 100us to write to the file. 

			/* Nodehub Stream ADXL100x data */
			if(PRINT_PERFORMANCE)
			{
				let t0 = now();
			}
			let ts = Date.now();
			log_ADXL100x.write(ts + ',' + nodehub_number.toString() + ',' + adxl100x_Sample_offset.toString()
			+ ',' + adxl100x_Sample + '\n');
			if(PRINT_PERFORMANCE)
			{
				let t1 = now();
			}
			if(PRINT_PERFORMANCE) console.log('\nPerformance '+ (t1-t0).toFixed(4) + 'ms');
			/* Nodehub Stream sensor data expect ADXL100x */
			if(adxl100x_Sample_offset >= 63){
				// current timestamp in milliseconds
				let ts = Date.now();
				if(PRINT_PERFORMANCE)
				{
					let t0 = now();
				}
				log_sensors.write(ts + '|' + deviceData.tempSensor.ambienceTemp.toString() + '|' + deviceData.nodehubTempSensor.temp.toString() 
				+ '|' + deviceData.nodehubStateSensor.state.toString()+ '|' + deviceData.nodehubStateSensor.g_value.toString()
				+ '|' + deviceData.nodehubBatterySensor.volts.toString() + '\n');
				if(PRINT_PERFORMANCE)
				{
					let t1 = now();
				}
				if(PRINT_PERFORMANCE) console.log('\nPerformance Sensors'+ (t1-t0).toFixed(4) + 'ms');
			}

I also disable the file writing in appclient.js and printed in the terminal and it misses data sometimes as well.

I attached the log file from collector and the file(test.txt) I write in appclient.js in the third collumn is data index and should be from 0 to 63.

Thank you,
