How should I ask my question?

Before you ask your question, please remember to check if it is suited for Nordic Developer Zone, and that it has not been asked before. Please search Nordic Developer Zone, if you find your question, please vote on it.

Here are some simple guidelines to get the best possible answers, fast, while helping others and improving your reputation, by getting votes.

A question should be clear and concise, leaving no doubt about what you are asking. Include details about what you have tried and exactly what you are trying to achieve. Avoid asking multiple unrelated questions in one question, ask them as separate questions.

Give a short description of your system and test setup. Include details about:

  • Hardware - evaluation kit, development kit, custom board, laser markings of the chip.
  • Software – SDK version, example or driver from SDK, protocol, SoftDevice version

If you get comments asking for more information or for clarification, edit your question to be as good as possible, fix mistakes, improve formatting, or clarify its meaning.

If an answer answers your question, accept it!

Additionally, this explains how not to ask your question.

  • Hello,

    I am working on Zigbee protocol.  In the zigbee stack, the structure is given for routing table. How can we add and remove the entries of node in routing table?

  • I am using nRF52832 and suddenly the board started giving error, this usb device is malfunctioned and the windows doesn't recognize it. I tried all the port, cables and different PCs also I updated the drivers but the problem is not resolved. Can someone help me in this situation?
