nRF5430,Nordic Distance Toolbox

When I compiled and flashed the Nordic Distance Toolbox example onto two nrf5430dk boards without changing any options, the following message appeared on one of the UART ports:
E: IPC endpoint bond timeout
E: Failed to send group init packet for group id: 0 strid: dm_rpc_grp err: -32
Not all groups are ready to use.
Another display:
*** Booting nRF Connect SDK v2.7.0-5cb85570ca43 ***
Using Zephyr OS v3.6.99-100befc70c74
Can you tell me how to get the distance measurement example running properly, thank you very much
