Light switch example not working on custom board

[norin saiyed]

Hi all,

I am using segger studio , i am trying to run examples of mesh alpha sdk that nordic provides. I can able to dump the code on board successfully. But if i try to dump light switch client example on my custom board, I will not be able to get it working. I have used Bluetooth Smart BLE4.1 NRF51822-A1 module from Radioland. Please help me.

Thanks in advance.

Hi Norin,

Could you try to program one of the BLE Peripheral examples from the SDK and see if that works?

yes i have tried.. it is working properly

Are you getting any error messages? Did you follow all the steps in Building the mesh stack?

[norin saiyed]

no i don't get any error messages. and i follow all the steps mentioned in  above link. i dump client code on  NRF51 development board and server on my custom board..on client side i receive no device provisioned.

OK. We suspect there might be an issue with the accuracy of the crystal oscillator used in the Radioland board. We recommend that you develop with one of the official Nordic Development kits as it makes troubleshooting easier.

However, you could try changing the required accuracy of the crystal in firmware:

examples/nrf_mesh_sdk.c line 191
nrf_clock_lf_cfg_t lfc_cfg = {NRF_CLOCK_LF_SRC_XTAL, 0, 0, NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}; 

You can find the valid defines in Infocenter.

How can i use internal crystal oscillator?? What changes are require in code to make use of internal crystal ?

Hi Norin,

Please take a look at this post for details.

i have made changes as per post but still did not  get anything working.. client  always shows no device provisioned. I am using RL52822-A1 module

[ketil]

OK. It would be beneficial to rule out any problems with the code before looking further into the RL52822-A1 module. Could you compile both the server and client on nRF51 DKs and verify that it works?

yes i am successfully compiled the code on nrf51DK and it is working properly. Is there any RAM settings required?
