ble advertising can't be searched by ios app on background

[freedom118]

Hi，

my ble device mcu is 51822 with sdk11，when my ios app on frontend，it can search the ble advertising immediately，but when my app runs on background，it can't search the advertising of the device。ios offical doc says that it supports ble scan on background while specified the service UUID. i don't know wether the device should do some special ble advertising setting for this？

Best regards.

hi, it is apple company identifier. to run the app in background in ios device. it is mandatory.
