Forming IEEE 802.15.4 Frames with Raw Link

[orangenlimer159]

Hi OpenThread Community,

This might be a dumb question..., but I've been experimenting with the transmission of MAC frames using the otLinkRawTransmit() function from the Raw Link API. However, I'm having difficulty in forming the IEEE 802.15.4 frame. Could anyone provide examples or guidance on how to do this properly?

Thanks in advance!

You can find some examples in mac_frame.cpp, which provides a number of methods for generating different types of MAC frames.

For example, take a look at:

openthread/src/core/mac/mac_frame.cpp

Line 1402 in c73829f

Error TxFrame::GenerateEnhAck(const RxFrame &aRxFrame, bool aIsFramePending, const uint8_t *aIeData, uint8_t aIeLength)
