Combining ble_peripheral code with peripheral (twi_scanner) code

[thoric_fish]

I am currently using the ble_app_template code from examples\ble_peripheral in SDK v10. The code and BLE read/write function successfully works. I now want to combine the ble_app_template code with twi_scanner code, because I am trying to use the nrf51822 to connect to i2c sensors, get the sensor data, and then send the data over BLE to phone.

I have successfully combined two peripheral examples programs before: twi_scanner and uart from examples\peripherals in SDK v12. I did that by combining the main.c and sdk_config.h code from both examples.

When I check the ble_app_template project in Keil 5, I cannot see a sdk_config.h file anywhere. I did some research and another post said the sdk_config.h is in the config folder for the project. But in Keil the config folder is not included under the project files for ble_app_template. How should I proceed? Thank you

Hi,

SDK 10 is very old and did not use the sdk_config.h concept yet. There are several other configuration files though (such as nrf_drv_config.h), which together constitute something similar to sdk_config.h. These are typically in a folder called "config". So if you stick with this ancient SDK, then look for those files instead.

Note that I recommend you use the latest SDK supporting your chip, which is SDK 12.3 for the nRF51.

Hi. 

I'm trying to combine ble_app_uart__saadc_timer_driven__scan_mode example with TWI_sensor example. 

I synchronized the project files in SDK, sdk_config.h files and even paths in the project settings, but I am still getting "missing definitions" errors. 

And I tried it both ways, putting ble_saadc code in TWI_sensor gives missing definitions in SoftDevice libraries, and outting TWI_sensor code in ble_saadc gives missing definitions in TWI libraries. However, all of these are included, and enabled.

Can you please guide me, on how to merge the two of these? 

Best regards
