Hi,  So I made a cert folder in the root of sd card and put the ca.pem file in that folder. Then followed the instruction of this page (from bosch site).  I exported the WiFi_firmware_update.zip and first flash and run the WifiHostProrammer. This output the messages "writing certificate /cert/ca.pem...file write complete" message. So this means the wifi module has been upgraded and the certificate has been read successfully. Then I flash and run the EnterprizeWifi. But the connection to the wifi is not established. Also no error messages.   What might go wrong? ... View more

I  have tried to find the variables which ontrols those parameters you mentioned, but no luck, got very confused. In the AppCoontroller.c, I  have the following sensor setup. could you please tell me what to add/change to get high frequency like your configuration. If this is not the target variable, could you please tell on which file  and what to change.         static Sensor_Setup_T SensorSetup = { .CmdProcessorHandle = NULL, .Enable = { .Accel = true, .Mag = false, .Gyro = true, .Humidity = false, .Temp = false, .Pressure = false, .Light = false, .Noise = true, }, .Config = { .Accel = { .Type = SENSOR_ACCEL_BMA280, .IsRawData = false, .IsInteruptEnabled = false, .Callback = NULL, }, .Gyro = { .Type = SENSOR_GYRO_BMG160, .IsRawData = false, }, .Mag = { .IsRawData = false }, .Light = { .IsInteruptEnabled = false, .Callback = NULL, }, .Temp = { .OffsetCorrection = APP_TEMPERATURE_OFFSET_CORRECTION, }, }, };/**< Sensor setup parameters */       Also, in the  appControllerSetup:     static void AppControllerSetup(void * param1, uint32_t param2) { ........ NoiseSensor_Setup(22050U); uint32_t samplingFreqency=500; ......... }     This samplingFrequency does not seems to have any effect. another related question: why only setup function for noise, where is other sensor setup function?     ...

Hi, I am concatenating each reading (accelometer and accustic) in a buffer array and sending them via wifi. Problem is, I am getting 7-8 milisecond (on average) time duration between two consecutive readings (reading and concatenating to the array but not sending it to wifi), even if set the    APP_MQTT_DATA_PUBLISH_PERIODICITY=1 here is my code for saving: if (RETCODE_OK == retcode) {   if (whileCounter<33){   tickNumber= xTaskGetTickCount();  length += snprintf(( char *) publishBuffer+length, APP_MQTT_DATA_BUFFER_SIZE, publishDataFormat,       tickNumber,     ( long int )sensorValue. Accel . X ,   ( long int )sensorValue. Accel . Y ,   ( long int )sensorValue. Accel . Z ,     sensorValue. Noise );         whileCounter=whileCounter+1;     }     else {       printf( "in the else publishBuffer len %d\n" ,length);     printf( "in the else publishBuffer size %d\n" ,strlen(publishBuffer));     whileCounter=0;     MqttPublishInfo. Payload =   publishBuffer;    MqttPublishInfo. PayloadLength = length;    length=0;     retcode = MQTT_PublishToTopic(&MqttPublishInfo, MQTT_PUBLISH_TIMEOUT_IN_MS); if (RETCODE_OK != retcode) { printf( "AppControllerFire : MQTT publish failed \n\r" ); }   } Any idea, Whyhy? ...

Hi, yes, I already set the APP_MQTT_DATA_PUBLISH_PERIODICITY   to 1 but still getting 7-10 reading on subsciber side.  I  am using a local MQTT server (Mosquitto 1.5.7).  To test the server speed and subscriber performance I created another publisher (using python and Paho library), and replace that with the XDK publisher, and that got more than 400 readings (also saved at the same time) without any issue. So, the server and subsciber is not a problem.  What I am thinking is, in XDK, it is sending data after each reading and during sending may be the sensor reading process is blocked. This might hamper the throughput. So, may be I should collect lets say 100 reading each time (save it in an array) and then send that.  Allthough, the test python publisher also doing the same (sending single data point) but that is on my computer with lot higher computation power (than XDK) and also may be sensor reading is bit more time consuming than creating just fake data. What do you think?  ... View more
