How do I clear the Attribute Table?

Yes, nrf_sdh_disable_request() is the gentle way. You can also call sd_softdevice_disable() directly. Using one of the two former calls avoids a reset, but calling NVIC_SystemReset() is also an option, but then you would have to use a retained register or a flag stored in flash to decide how the ATT table should be populated.

Are all of the libraries coded to support this case properly (nrf_sdh_disable_request I assume), or would it be better to do it using NVIC_SystemReset? Thanks!

HI James,

the only way to clear the Attribute table is to uninitialize the BLE protocol stack and then reinitialize the BLE protocol stack and then add the new services/characteristics/descriptors using sd_ble_gatts_service/characteristic/descriptor _add().

Best regards
