I started with the template app and added BLE services, and I'm continuing by adding a TWI sensor (I2C). I know there is a TWI_sensor example, but I already had some working code for this particular sensor (accelerometer). There's a couple of mentions of this compile error on devzone, but I have not been able to make their suggestions work for me.
../../../../../../modules/nrfx/drivers/include/nrfx_twi.h:73:35: error: 'NRFX_TWI0_INST_IDX' undeclared here (not in a function);
It looks like perhaps NRFX_TWI0_ENABLED is false or not defined? But in my <sdk_config.h>, I have the following:
#define NRFX_TWI_ENABLED 1
#define NRFX_TWI0_ENABLED 1
#define NRFX_TWI1_ENABLED 1
#define TWI_ENABLED 1
#define TWI0_ENABLED 1
#define TWI1_ENABLED 1
I've tried only enabling the nRFX_TWI drivers and disabling the TWI driver. I've also tried it the other way around. But it didn't fix the issue. Am I mis-interpreting the compile error?
