Setup toolchain to build first example Mesh SDK

[Giang]

Hi all , I am beginning with MESH SDK on Window . I use NRF52832 board with Softdevice S132v3.0 on KeilC5 . I read instructed at infocenter.nordicsemi.com/index.jsp but I dont understand what to install ? Please guide me how to install the tools to build first example Mesh . Thank very much

Hi,

To build the Mesh SDK example applications, a toolchain based on either CMake or SEGGER Embedded Studio is required. For quickly getting the example code up and running with full debug capability, it's easiest to use SEGGER Embedded Studio.

Please see the SEGGER Embedded Studio website for download and installation instructions.

You would need minimum a 32Kb RAM nRF51 or nRF52 device to run the both the Mesh stack + the SoftDevice stack.

The light_control_client uses 13.1 kB RAM, + you need about 8 kB RAM for the SoftDevice. 13 + 8 = 21 Kb, so it will not fit into a 16 kB RAM device. If you want to still use the nRF51822 you could go for the nRF51822 QF AC variant with 32 kB RAM.

Hi Sigurd,

Is there any of the mesh sdk examples that fits into a 51822 QF AA?

Thanks

No, 

You would need minimum a 32Kb RAM nRF51 or nRF52 device to run the both the Mesh stack + the SoftDevice stack.

E.g the light_switch_server example uses about 15 kB RAM in the latest Mesh SDK, + you need about 8 kB RAM for the SoftDevice. 15 + 8 = 23 Kb, so it will not fit into a 16 kB RAM device.  If you want to still use the nRF51822 you could go for the nRF51822 QF AC variant with 32 kB RAM, but I would recommend using the nRF52832 with 64 kB RAM if you are developing a mesh application.
