The Quanta 5 firmware update has a following specific: it is necessary to check the compliance of the frequencies used with the regulatory domain restrictions, which appear in version 2.0.0. In the automatic center frequency selection mode, in case the frequency grid is wider than the range allowed by the regulatory domain, this will be detected immediately after the update, as a result the link will remain in the "Init" state. To restore the connection, manually correct the configuration by narrowing the frequency grid or changing the regulatory domain.
To upgrade to version 2.0.0 or higher without the loss of the communication, use the following methods.
The best way is to pre-check and adjust the available frequencies grid to meet the requirements of the selected regulatory domain. In this case, the edges of the spectrum at the selected channel width should not go beyond the regulatory domain range. For example, for the FCC_5.8 domain and 56 MHz, the frequency grid should not be wider than 5745-5830. However, calculate the correct frequency grid can be very difficult without prompts that appear in version 2.0.0. Therefore, we offer additional methods for a secure update.
Перед обновлением на обоих устройствах измените регуляторный домен на "Rest of the World", что фактически будет означать отсутствие регуляторных ограничений. После завершения обновления верните требуемые регуляторные домены. Отметим, что в некоторых случаях домен "Rest of the World" может быть недоступен пользователям.
