Q: Is it possible to run ESP8266 at 40MHz or lower instead of 80/160MHz. While underclocking NO Wlan is required? Pls provide code example if possible.

A: ESP8266 currently does not support frequency adjustment, it is stated in the esp_pm_config_esp8266_t structure. In addition, you can try esp32c3, which supports frequency adjustment, BLE, and has more memory.
