LLCC68

Will it work with the LLCC68 chip?

I have never tried the LLCC68 but it seems like it should. Basically the same as the sx1262

Hello. I was able to run the E220-900MM22s module built on the LLCC68 chip. But it only worked after editing the code sx126x.cpp, line 161: (if (strncmp(this->version_, "SX126", 5) != 0) {) on (if (strncmp(this->version_, "LLCC68", 5) != 0) {). As I understand it, this is a chip check, can add a check to the code for either SX126 or LLCC68?

Ah right.

There is also a hw_version enum:

          cv.Required(CONF_HW_VERSION): cv.one_of(
                "sx1261", "sx1262", "sx1268", lower=True
            ),

  if (this->hw_version_ == "sx1261") {
    if (pa_power == 15) {
      uint8_t cfg[4] = {0x06, 0x00, 0x01, 0x01};
      this->write_opcode_(RADIO_SET_PACONFIG, cfg, 4);
    } else {
      uint8_t cfg[4] = {0x04, 0x00, 0x01, 0x01};
      this->write_opcode_(RADIO_SET_PACONFIG, cfg, 4);
    }
    pa_power = std::max(pa_power, (int8_t) -3);
    pa_power = std::min(pa_power, (int8_t) 14);
    buf[0] = 0x18;  // max 80 mA
    this->write_register_(REG_OCP, buf, 1);
  } else {
    uint8_t cfg[4] = {0x04, 0x07, 0x00, 0x01};
    this->write_opcode_(RADIO_SET_PACONFIG, cfg, 4);
    pa_power = std::max(pa_power, (int8_t) -3);
    pa_power = std::min(pa_power, (int8_t) 22);
    buf[0] = 0x38;  // max 140 mA
    this->write_register_(REG_OCP, buf, 1);
  }

can also add llcc68 there, I guess it should do the same thing as sx1262?

Do you want to submit a PR for this? I can merge it. If not I can do it sometime.

I specify SX1262 in the settings.

Take your time . You can do this later .
