2 years ago I find a possible solution. After testing using a arduino lib compatible with my module, i found tcxo Voltage is 3.3v. Even making this change, still not succeeding in putting the module on standby, however I implemented a routine for it to try again if the command returns failure and apparently solved the problem.
for (uint8_t retry = 1; (in == 0xaa) && (retry < 10); retry++)
{
gpio_set_level(SX126x_SPI_SELECT, HIGH);
WaitForIdle(BUSY_WAIT);
gpio_set_level(SX126x_SPI_SELECT, LOW);
spi_transfer(cmd);
in = spi_transfer(data[n]);
if (debugPrint)
{
ESP_LOGW(TAG, "RETRY: Try=%d", retry);
ESP_LOGW(TAG, "RETRY:WriteCommand: CMD=0x%02x", cmd);
ESP_LOGW(TAG, "RETRY:%02x --> %02x", data[n], in);
}
}After this return is for me

Do you remenber this port expension board lost on the way to Japan ? @nopnop2002 have a good laugh :)
I have a same issue that previous, but in a different module. I use a Ebyte e22-900m22s module, that have a LoRa chip llcc68, its seems a semtech 126x. The data from this devices is here and here. Output from my log.
I decided to remove the while(1) lock for when an error occurs, in order to check if all registers generated errors, I noticed that not all of them, here is my output:
I noticed that the possible problem for the previous question was in tcxoVoltage, however I didn't understand how this parameter works and what value exactly I have to configure.
