nRF52832 NRF_FAULT_ID_SD_ASSERT @PC 0x000071CC

[CBeixa]

This is a product based on nRF52832,which uses PA/LNA.

The device resets in Bluetooth advertising state. the ID is 1 (NRF_FAULT_ID_SD_ASSERT), the PC is at 0x000071CC, and the info is 0.Oddly, no reset observed in connected state, despite non‑connectable advertising being enabled post‑connection.

Environment information:

nrf52832,

ANT_s332_nrf52_5.0.0.hex

nRF5_SDK_14.2.0_17b948a

How should I analyze? What kind of problem is there?

Hi,

Asserts in the SoftDevice typically means the BLE stack has been prevented from running for too long.

Are you disabling interrupts (for more than a few μs), or have any interrupts at highest priority?

The first step would be to look at those. Either eliminate them, or make sure they are short enough (and/or prioritized low enough) that the BLE stack is allowed to run frequently enough for it not to overstay its hard time limits.
