S99 Firmware Upgrade

S99 V1.08 Firmware update description

1.Cancel startup delay.

2."Protocol"Added PD 15V option.

3."Brightess" range is updated from 1 to 10.

4.Do some optimization.

5. Special note: Soldering iron does not always automatically select the correct protocol and voltage Settings, this is not a problem of soldering iron or firmware, but depends on the quality of the usb cable and charger used, as well as the chip used in its production.

If the soldering iron restarts, which can usually happen if You use high power 2.5 Ω tips with a less powerful charger, try another "Protocol" option to lower the voltage. If that doesn't help, try reducing the Power percentage, "power" regulation works on some sources, not all.

The PPS protocol is recommended for 2.5Ω soldering tips, and the PD protocol is recommended for 5.5Ω soldering tips. The PD20 protocol setting can also be selected using  2.5Ω tips with some powerful chargers to achieve the maximum power of the soldering iron with them.
