Linux/CC1350: How to send a string value from sensor to the collector in the 15.4 linux stack?

Siddhant Sinha

Part Number: CC1350

Tool/software: Linux

I am following the Sub-1 GHz Sensor to Cloud Industrial IoT Gateway Reference Design. It sends integer values from the sensor to the cloud. But instead of integer values, I want to send strings that I read from a txt file stored on a sd card. How shall I wrap the the strings in the sensor code and send them. Also what changes do I have to perform in the collector code to receive the strings.

As I know, you can read the txt file byte-by-byte into a buffer and send the buffer with Sensor_sendMsg

I am using this wiki page as a reference: http://processors.wiki.ti.com/index.php/Adding_New_Sensor_Support_To_Sub1GHz_Sensor_To_Cloud_Linux_Gateway#Sensor_To_Cloud_-_Running_Final_Version_with_Generic_Sensor , what changes do I have to do in the smsgs.h file?

I think you only need to fill txt data in pMsgBuf and count len,and use API "Sensor_sendMsg(Smsgs_cmdIds_sensorData, pDstAddr, true, len, pMsgBuf)" to send the buffer

But how will the collector receive it in its buffer? There has to be some change in collector code in order to receive the data.

As according to this wiki processors.wiki.ti.com/.../Adding_New_Sensor_Support_To_Sub1GHz_Sensor_To_Cloud_Linux_Gateway, there are changes to be made in the collector code as well as the nodejs code.

I see the TI wiki already gives very detail steps. What do you still need?
