hi everyone
After using Android nRF Connect FOTA, the settings storage partition of my device was erased, which means that my device's PAIR information was lost and the device cannot be reconnected.
I am currently using ncs v3.0.2，Use external flash as the MCUBOOT_SECONDARY partition。
Here are my pm_static.yml
mcuboot:
address: 0x0
size: 0xc000
region: flash_primary
mcuboot_pad:
address: 0xc000
size: 0x200
app:
address: 0xc200
size: 0xefe00
mcuboot_primary:
orig_span: &id001
- mcuboot_pad
- app
span: *id001
address: 0xc000
size: 0xf0000
region: flash_primary
mcuboot_primary_app:
orig_span: &id002
- app
span: *id002
address: 0xc200
size: 0xefe00
settings_storage:
address: 0xfc000
size: 0x4000
region: flash_primary
mcuboot_secondary:
address: 0x0
size: 0xf0000
device: XT25F32B
region: external_flash
external_flash:
address: 0xf0000
size: 0x310000
device: XT25F32B
region: external_flash
Here are my my prj.conf
I feel like every upgrade is successful, but I deleted my pair information. After upgrading at the same time, it always prompts GATT ERROR (0X85)
