Problem!! in Twi driver master intance

[Urvisha Andani]

Hello All

I am working on nrf52832. right now i am try to combine peripheral twi sensor program and ble_app_template. Because in my application use LM6BD temprature sensor connect with nRF52832 through i2c and take reading of sensor and then I try to read that data in device(Phone) for that i create custom service.

My problem is when i try to debug this program which is combination of that 2 program at that time:

'NRF_DRV_TWI_INSTANCE_0' undeclared here (not in a function); did you mean 'NRF_DRV_TWI_INSTANCE_'?

i got this error. But i already define this variable in main program.for example  #define TWI_INSTANCE_ID     0

and this error got in below sentence

#define NRF_DRV_TWI_INSTANCE_(id)   NRF_DRV_TWI_INSTANCE_ ## id.

So give me some idea for solving this error.

so please help me solve this error..

HI Urvisha,

Happy New Year 2019...

did you try to read the sensor data with TWI - code and then try to interface BLE - UART to get in phone.
