ESP32_Devkit-V4 try to change/reduce transmitting power

Postby bithalver » Sat Nov 27, 2021 10:05 pm

Hello,
with VSC /PlatformIO / esp_wifi.h I'm trying to reduce the transmitting power. esp_wifi_set_max_tx_power(20) results in no difference to esp_wifi_set_max_tx_power(2). The current consumption of the board shows no change. What am I doing wrong?

tnx

Code: Select all

Param power unit is 0.25dBm, range is [8, 84] corresponding to 2dBm - 20dBm.
2 is invalid. Check your return values.
