Question of the "flexcan_pretended_networking_wakeup" about frdmmcxn236

[yhc123]

I'm looking the "flexcan_pretended_networking_wakeup" case of SDK_25_03_00_FRDM-MCXN236, and I want to know what's the meaning of wake up payload range in the readme file, 0x0055000000000000 seems like a 64bit data but the platfporm just 32bits.

Does the payload for sending data need to be between 0x00550000000000 and 0x005600000000000 for the receiving end to receive it? Why receiving end can reveive the match message 2 and  match message 1, they are out of range maybe.

Hi @yhc123,

The wake-up payload range is set as an example of how to define a range for the pretended device to be woken up. However, this is only an illustrative method, as it is not actually used on the wakeup procedure. In the example, as long as 4 messages are received, the device will wake-up.

BR,
Edwin.
