UWB MAC Custom Session

tomzzzz — Thu, 19 Sep 2024 09:06:56 GMT

Prerequisites:
NCJ29D5 both ends now use AIO's SDK, and the functions and functions related to Customized Session have been enabled in the APP code, the low-power mode has been disabled, and nothing else has been modified.
Problematic:
1. Now the parameters configured by Responder RCM_RX_TIMEOUT configurable time in the NXP_UCI_CCC_Specification description can be configured from 50us-40000us, but now the configuration parameters cannot take effect from the current waveform, and the configuration is the same as 40000us and 20000us, resulting in the RX on time is too short.
Do other parameters need to be configured together to take effect?

2.The ranging can be started normally, but the ranging status code received on the initiator side is shown as follows
0x2: Transaction expired
The ranging status code received in Responder is shown below
0xF: Ranging Control Message lost (Not available for the controller)

The following is the configuration of the SET_APP_CONFIG_CMD parameters of the initiator

Hello,

Sorry for the inconvenience this might cause you but as the information of these products it's under NDA (Non-Disclosure Agreement) the information it's not public, this is not a secure channel to share any information of this device and I do not have the data as well for the same reason.

For more information about the chips and buying process, could you please contact one of our distributors available in the Distributor Network|NXP? They can not only help you with the NDA process, but also help you check if you can get documentation and the information they can offer you.

Regards,

Ricardo
