Does LR mode use multiple subcarriers and thus have to lower peak level? Any details on LR mode modulation? Sensor: http://www.herbert-dingfelder.de/?page_id=68 80...

ESP32 LR mode default PHY rate for ESP-now packets

I am not calling esp_wifi_internal_set_fix_rate(). In normal mode, I see ppkt->rx_ctrl.rate = 0 which I suppose is WIF...
