RTOS/CC2640R2F: [ Sending Measurement Data over BLE - NOPOSIX]

Hello

I'm doing the SimpleAcademy to understand how i can send temperature and humidity values over BLE to a phone or a beacon, and i'm trying to do the "BLE + TI Drivers". But, almost in the end of the exercise, i can't send values to my smartphone. The error is :

"../Application/myThread.c", line 82: error #20: identifier "MYDATA_DATA_ID" is undefined
"../Application/myThread.c", line 82: error #20: identifier "MYDATA_DATA_LEN" is undefined

Best regards

Hi Diogo,
The error states that the identifiers are undefined. Have you defined MYDATA_DATA_ID and MYDATA_DATA_LEN?

Yes, They are defined in service mydata.h

Have you included the mydata.h to the C file?

If i put the #include "myData.h" in MyThread.c, it gives me lots of errors, like this: line 127: error #20: identifier "bStatus_t" is undefined

I put it in SimplePeripheral_performPeriodicTask to send the data through BLE.
Another question is. In BLE, the data cames in ASCII. It's possible to read the value at phone in DEC ?

Hi Diogo,
I believe this error is self-explanatory: error #20: identifier "bStatus_t" is undefined

You will need to add define bStatus_t or include the file that defines it.

The transmitted data is in hex either way, so you can format it the way you want.

Hello.

I solve the problem by including

#include "icall_ble_api.h"

#include "devinfoservice.h"
#include "simple_gatt_profile.h"
#include "ll_common.h"
#include "myData.h".

About the output format. I used myData = (((myData & 0xFF) << 8)| (myData >> 8) & 0xFF);

Hi Diogo,
I am not sure I understand your last statement. The only thing you are doing is reversing the MSB/LSB, i.e. 0xABBA to 0xBAAB. You should send the data raw, to reduce filtering on the embedded side and do the formatting on the smartphone side.
