I’m trying to use the DW1000 modules to implement a time synchronization system for nodes in a wireless network.
I want to use the pulses generated on the SFDLED pin to capture time stamps on a microcontroller. But in the DW1000 module user’s manual it is not specified what is the delay from the moment the receiver module detects the SFD until the SFDLED pin is activated.
The user’s manual specifies how to configure the duration of the pulse generated at the SFDLED pin, but it does not indicate the delay from the SFD detection to the SFDLED pin activation.
Is this delay characterized or described in any document?
