I found a photo of the board. It looks like the bluetooth chip is
under some shielding, but the FCC ID is printed:

In the internal photos FCC document they remove the shielding,
revealing the chip underneath. It's unlabeled:

. This document also hilights where the antenna is.

This is a lot of pdf files to look at on my tiny raspi. This document:

says this:

> The Raspberry Pi 4 Model B+ module has an IEEE 802.11b/g/n/ac 1x1 WLAN, Bluetooth 5 and
Bluetooth LE module based on the Cypress 43455 chip.
