SX1262 continuewave

[Rinthes]

Regarding the use of the continuous wave mode of the SX1262, when using the CW mode, the normal configuration parameters are set and the transmitDirect() function is called, but this feature cannot be used properly. No valid output is detected when tested with a power meter. However, using the same configuration for TX results in a valid output. I hope to receive some support.

void LoRa::Config(float feaq, uint8_t cr, float bw, uint8_t sf, uint8_t preamble_len, uint8_t power, uint8_t lora_mode) {
    int16_t state = radio_->begin();
    if (state != RADIOLIB_ERR_NONE) {
        ESP_LOGE(TAG, "SX1262 init false: %d", state);
        return;
    }
    // 设置频率
    state = radio_->setFrequency(feaq);
    // 设置调制参数
    state = radio_->setCodingRate(cr + 4);
    state = radio_->setBandwidth(bw);
    state = radio_->setSpreadingFactor(sf);
    // 设置帧格式
    state = radio_->explicitHeader();
    state = radio_->setPreambleLength(preamble_len);
    state = radio_->setCRC(1);
    state = radio_->invertIQ(false);
    // 设置发送功率
    state = radio_->setCurrentLimit(140);
    state = radio_->setOutputPower(power);
    
    lora_init_is_success_ = true;

    // 设置lora模式
    radio_->transmitDirect();

}

This report is missing key information for me to be able to help you. I have no idea what is "normal configuration" for you or what arguments are you passing into your config method, so I don't know whether you are passing some invalid values. Neither do you as a matter of fact, as you ignore all of the retuned status codes, so if any of them methods fail, you won't know. A lot of them also have no influence over direct transmission whatsoever.

I suspect the real problem is somewhere in the code you are not showing - you have not shown what happens afterwards calling the functions, so my guess is that you disable it before being able to measure the output.

I tested with a known good SX1262 and I see the output with an RF power meter, so this is most likely a usage problem.

Would you mind providing a usage example of the continuewave mode for reference? I would greatly appreciate it.
