leaps_usr_data_read
Read user data from the node. To be notified on new user data received on the UART/SPI or BLE enable corresponding event by leaps_int_cfg_set and leaps_ble_evt_cfg_set respectively which will set dedicated flag in the status and also cause generation of an event on UART/SPI or BLE.
type: ? 2 bits ? (user data type)
‘0’ means read user data that has been written to UWB interface from other interfaces like BLE, SPI, UART
‘1’ means read user data that has been written to BLE interface from other interfaces like UWB, SPI, UART
‘2’ means read user data from non volatile memory
data: (the user data bytes up to 250 bytes depending on the type)
Example 1 (read UWB user data)
