Application production release guidelines.

[Yadhu KP]

Hi,

we are in the pre-production stage and going for the final production release of our application code based on ble_app_hid_mouse example, in this stage I would like to know whether there exist any guidelines or checklist to make sure the application code more stable for production, this is our first product using nrf52832 and SDK 17. I am listing some of the steps followed below.

• We were using NRF_LOG for debugging purposes in both the backend UART and RTT, so we disable it from sdk_config.h
• removed DEBUG preprocessor definition.

Hi,

We have a production Production Programming  whitepaper, https://infocenter.nordicsemi.com/topic/nwp_027/WP/nwp_027/intro.html , but nothing on how to get your own firmware code production ready. It might be difficulty to create such a guideline/checklist, since this would depend a lot on your own code and product. But your list so far makes sense, and they are good points. Another point could maybe be to do some power consumption testing, to see that it draws the expected amount of power.

Hi,

thanks for the reply, do you have more info on this topic power consumption test, is it in any way related to firmware optimization, can you elaborate on the point. like how we can effectively test it or what are tools we may need.

 Yes, or perhaps more accurate would be power optimization and validation. See this webinar: https://webinars.nordicsemi.com/become-an-expert-on-power-profiling-6 and this video: https://www.youtube.com/watch?v=B42lPvkUSoc

Here is the PPK-2 you can use to measure power consumption: https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2

If you are developing a product that is powered by a battery, you want to measure the power consumption, so that you can get an estimated battery time before recharge/replacement for you product.

thanks for the input, I think  i will get PPK-2
