Tools and software versions that are required for developing BLE products with nrf51822 modules.

[SChary]

Hi,

I have purchased an nRf52DK set for developing BLE applications. I am using the Segger Embedded Studio (SES) with GCC and SDK version 16 for development.

I have two questions:
1. I have a few nrf51822 modules that I bought a while ago.  Can I develop code for these modules in the setup that i have ? If not, could you please let me know the setup - Soft device version, SDK version and programmer that I will need to use these modules.

2. How can i check if these modules have a boot loader inside ? If that exists, can i program them over serial port and how to it?

Thanks and Regards

Hello Chary BS;

The errors you are getting indicates that the flash placement is indeed missing and / or wrong.

I hope it is in the right place - i saved it  in the example folder for ble_app_uart.

 The flash_placement file needs to be located next to the Segger Embedde Studios project file - ie in the directory SDK\examples\ble_peripheral\ble_app_uart\pca10028\s130\ses\
Please relocate the file to this location.

With the file in this location, please right click your project file in SES, click options and go to the linker settings. There should be an alternative for "Section Placement File" that should point to your flash_placement.xml file.

What changes did you make in the linker settings?

Best regards,
Karl

Hi Karl,

Thanks for patiently staying with me :) on this issue.

Due to time to market pressure, i have had to drop the idea of using the 51822 and go for the 52832 instead.

Hence I would request you to close this ticket and I will pursue the same product development on the newer chip.

Maybe just for the sake of getting closure I will revisit this device in the near future, when there is no pressure to get a product out, and get a working appliance out of it to justify the investment :).

Thanks again.

Regards

Hello again Chary,

Sorry for my late reply - I have been out of office for some time.

I am glad to hear that you were able to finally build your project successfully!
Do you have any updates on how it went yet?

Please do not hesitate to open a new ticket in the future if you should encounter any other issues or questions!
