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

Good morning Karl,

Just wanted to know how to find out my chip revision number. Part number says N51822QAAH01588EE. Is there any part selection guide for identifying the revision in this number?

Oops, Sorry for my mistake - the chip on my module has the number N51822 QFAA H 01518 EE.

You can check the part number against the IC revision and variants matrix to figure out which revision you are working with.

Do not hesitate to let me know if you should encounter any other issues or questions.

Good luck with your development!

Best regards,
Karl

This is the board i am using. - https://www.waveshare.com/core51822.htm

under the heading "Revision History", it says

"2015.06, Core51822 upgrades the onboard chip to Rev3, features 32kB RAM, supports higher version SDK, and all the demo codes are still compatible with the Rev2 ones."

So i guess i need not worry about the compatibility issues, hopefully..

Now that you know which IC revision you are working with then you may confer with the Compatibility matrix I referenced you earlier, to see which SDK and SoftDevice versions your SoC is compatible with. If you use the versions as documented in the matrix then you will not see any compatibility issues between IC Rev, SDK and SoftDevice version.

Best regards,
Karl
