Hey Richard! Here's a log from a partial battery charge in the following conditions:<div><br></div><div>- XO 1.5HS using the firmware you sent</div><div>- Connected to an unregulated 10W panel</div><div>- Using the script rtcwake-log you sent I think it was from december last year</div>
<div>- The first couple hours the panel had no direct sunlight</div><div><br></div><div>Unfortunately, since the panel was a sample I couldn't modify it to measure actual current or voltage from the panel.</div><div>
<br>
</div><div>Quick comments:</div><div>- The XO charging light was always on with the panel conected, even with very low light.</div><div>- When the battery was full, the XO started doing that buzzing sound, like when it works with a low voltage, only this time it was louder than in that situation. I'm guessing maybe as the battery wasn't charging the panel reached close to open circuit voltage and there was some pretty heavy regulation going on?<br>
<br></div><div>Just from this one, I would say that the firmware worked great! It's a pitty I cannot verify with hard numbers the MPPT function.</div><div><br></div><div>Ismael</div><div><br></div><div>P.S. No problems upgrading the firmware with this version</div>

This one hopefully fixes the keyboard issues. Anyone who experienced<br>
that problem please reflash your previous firmware and then flash in<br>
this new one.<br>
<br>
Thanks.<br>
