Communicate Data Via BLE only between 2 devices

Hi,

Most probably this is due to one or more of the following reasons:

The config file hasn't been configured properly. Diff your config file with the TWI example config file, and see what's different.
The path to the added source file isn't included in the project settings.
The proper header/source files haven't been included.

regards

Thank you. Now I can communicate with 2 devices via BLE.

But I am getting errors while combining 2 programs(Twi read program and Ble communication Program)

I have updated Config.h file and Included other .h and .c files.

It successfully Builds when there is No function in main.c for TWI communication.

But if I add any function of TWI to the main.c it shows errors and doesn't build.

For example when I use the function "twi_master_nit()" which was exactly used in the separate TWI program. it shows the following error.

Hi,

You can start with the ble_app_uart example which instead of TWI uses UART. After you have understood how that example works, you can try to merge the TWI scanner example into the ble_app_uart example and replace the UART part with TWI. Try to search in the forum, I'm pretty sure this has been discussed before.
