I cannot connect Application board 3.0 and development desktop 2.1 via bluetooth.
But I can connect Application board 2.0 and development desktop 2.1 via bluetooth.
Could you please help me to solve this issue?

Hi,

Sorry, Additional question again.

Is it possible to add the Sensor time data or Sensor index information to printf data?
The sensor time is the same as the sensor time of the CSV file obtained with Development Desktop 2.1.

If possible, could you please provide us the sample c source code?

Hi,

You can change the limit number from 100 to the number you want. Please note that  the type of var is uint8_t which is from 0 to 255. If you want to get higher value, you can change uint8_t to uint32_t. Then you should get many samples reansferred from APP3.0 to PC through BLE.

Regarding timestamp in your data log file, the MCU mode of COINES can only support the timer in milliseconds. You can use the function "coines_get_millis()" to get the ms of MCU timer and transfer the time format you like.

There is a example of get and print MCU timer in ms uint.

uint32_t timestample = 0;
timestample = coines_get_millis();
printf("timestample = %lu", timestample);

Thanks.
