Ah! That sounds much more likely.<br>
<br>
Is there an error (timeout) path that might be freeing the buffer
when it's still in use?<br>

Hi Greg, welcome :)<br>
<br>
Juliens parameter #0 has been overwritten with "Topping o", which
is part of the charge status message ("Topping off").<br>
<br>
So it's much more likely we've got a buffer corruption bug that's
triggered by (maybe) bad connectivity situations.<br>
<br>

Hi all,<br>
<br>
New here, so this may be totally off the wall.<br>
<br>
I notice that the first example, with a "5" going to a "k", it
may be more easily explained as a bit <b><i>shift</i></b>
instead of a set of flips. Is there anywhere in the system
where the bytes are clocked serially between devices, where
there may be some marginal timing?<br>
<br>
Just a thought.<br>
<br>

Strange. Seems more than a simple bit flip. I haven’t seen this myself, or heard of it much from other users.
Is the Twizy code using EEPROM for anything other than settings storage? I know that there are a very limit number of write cycles into that EEPROM space.
I did some googling, but all I can find is corruption during writing (either power down, or interrupt during write). But, for our case of very very rare EEPROM writes, that shouldn’t be an issue.
Regards, Mark.

The EEPROM data loss is a known issue, and I'm afraid there's nothing we can do about that. It seems to be a bug in the PIC18.

<pre wrap="">Hi all,
Thanks to Michaels last message to remind me to ask a question here:
Since a few months, maybe a bit more because it happens only once in a while, I have noticed I wasn't receiving the SMS alerts (feature on SMSIP mode) , and sending a "Stats?" only gave me the nasty access denied answer.
It turns out, using the application, I noticed that the phone number was getting corrupted (afaik, it's the only setting affected)
Normally: "+33651886877" it became "+336k1886877" or "+33651886Z77" etc... like a solar flare bit flip !_______________________________________________
