Am a beginner to this platform , i don't know how to made the conversion . can anyone help me

Hello Reeshma

We have made an updated version of the nrf5-ble-mpu-simple project found on Martins Github github.com/.../sdk13

So the mpu-simple project should now work with SDK13. Please note there have been some changes in the "how to use" section, be sure to read through it and follow the instructions there.

EDIT 28.04.17:

Makefile for the nrf-ble-mpu-simple project added.

Make sure the path to the project folder is: [SDK folder]\examples\nrf5-mpu-examples-sdk13\nrf5-ble-mpu-simple\

Make sure to place the two files at path: [SDK folder]\examples\nrf5-mpu-examples-sdk13\nrf5-ble-mpu-simple\pca10040\s132\armgcc

A modification must be made to the file ble_mpu.h: Add a second set of braces around the BLE_UUID_BASE_UUID initializer, it should read

#define BLE_UUID_BASE_UUID              {{0x23, 0xD1, 0x13, 0xEF, 0x5F, 0x78, 0x23, 0x15, 0xDE, 0xEF, 0x12, 0x12, 0x00, 0x00, 0x00, 0x00}} // 128-bit base UUID

When written with a single set of braces I received an error due to armgcc being picky. This workaround was described here devzone.nordicsemi.com/.../

With these files I was able to compile the project in windows.

Makefile

ble_app_template_gcc_nrf52.ld

Best regards

Really thanks alot sir, i will try it with the above code

hi sir , am compiling it in embedded linux using the arm gcc , i cannot able to find the make file for the nrf -ble-mpu-simple- , eventhough i have tried alot to make a makefile , but it throws only an error...how can i create the make file..?? sorry am a beginner to this platform , can anyone please help me..
