Data reception using 802_15_4_lib_gcc.a

[AndersLundqvist]

Hi,

I am using the nRF52840 DK and the wireless_uart example from nRF5_SDK_15.0.0 to try and receive data from other 802.15.4 sensors. Using the example I can receive messages in the mcps_data_ind function if I am using two development kits but not receive any data from other sources.

I have set the PANid to 0xFFFF and have omitted security but still no sign of any data. Using a sniffer I can see that there is plenty of messages flying around and that both DKs send plenty of messages even though they contain no payload data i.e. no data has been received on the uart. However these messages cause no action on mcps_data_ind either. Only when there is a data payload the mcps_data_ind gets called.

I really need to gain access to these messages. How do I do that?

Is the source code for the 802_15_4_lib_gcc.a available somewhere?

Best regards

Anders

You could say that I am trying to create a sniffer for ALL 802.15.4 messages, not only those with payload...

Additional information: The other sources send their messages as MAC commands (0x43/0x63 instead of 0x41/0x61 which is data).

I would like to get access to those messages!

I'm afraid we do not have the source code. We use a 3rd party MAC layer from Luxoft. The API documentation is found here:  IEEE 802.15.4 stack API.
