Lab testing and Certification for a Global product (CE, FCC, etc...)

[alplayer01]

Hi,

I’m using a pre‑certified ESPRESSIF ESP32-C3-WROOM-02-N4 in a product. Firmware currently enables BLE, and only starts a Wi‑Fi access point when OTA update is needed. The Firmware doesn’t set country, channel range, or transmit‑power explicitly.

Questions:

- For selling in multiple regions (mainly US & EU), do I need to change the firmware settings for WiFi/BLE? or is using a pre‑certified module with default settings is enough?
- Usually, when sending a few units (that has a pre-certified ESP32-C3 Module) to a testing Lab, do we have to use ESPRFTestTool? or they will just test for EMC/EMI, since the module is already pre-certified?

I contacted a few labs, some of them gave good answers, while others created more confusion.
This is why i'm posting here, hoping to find an answer from experts who have experience with this. Any help would be greatly appreciated (I don't have a technical background).

Thanks!
