We don't have any official support for this, but you can have a look at this old unofficial project that uses the RADIO directly for BLE advertising.

I want to know if the Nrf52832 chip can implement this function. If it can, please help me, buddy.

Hi,

The BLE protocol has strict timing and formatting rules, and using the Bluetooth stack guarantees BLE compliance, with robust and reliable behavior. The nRF52832 has 512 KB flash, and e.g. the S112 stack will take around 100KB, so you still have 80% of the flash to your application.

Since the Bluetooth protocol stack occupies flash memory and RAM, and also increases programming time, and given that I only need to send broadcast packets at regular intervals (similar to how 2.4G works) without using any other Bluetooth functions, I don’t think it’s necessary to use the protocol stack.

Hi!

Why? I strongly recommend using the Bluetooth stack for this.
