Hi Bdale,

Thanks for the quick response. To continue.

I think I'll take you up on that offer but it would be October at the
earliest as we're still in flying season and crop is now getting to optimum
rocket hiding levels. I will then need the unit back by March as April is
THUNDA over in Queensland and I will require it then. I'm planning on
ordering another TeleGPS (v2.0 this time) as well as a new TeleDongle
Starter Pack with the v3.0 TeleDongle so it might make sense to order the
new kit after returning my old TeleDongle to consolidate shipping costs. I
might also request a pair programming cable to be included for future use
as I also own a TeleMetrum v1.2 and to update that requires that cable. I
did have one but IIRC I loaned it to a guy at Balls in 2013 and never saw
it again.

I'd be curious to hear from Keith regarding this as well. Sadly I don't
have access to any other ground station hardware at the moment but I might
know one or two around the traps that I could get my hands on. I suspect
they'll all be similar to mine in terms of versioning though as they would
have been purchased from Blake at Australian Rocketry when he brought a
whole slew of TeleMetrum v1.0 and v1.2 Starter kits.

Yes, I have tried it. I get no comms link when I plug in my TeleDongle to
my phone via an OTG cable. As mentioned with earlier variants (I'm assuming
v1.7 or before) everything just automatically worked just like on on my
laptops as my TeleDongle starts up on the channel I've configured the
TeleGPS to communicate over. With v1.8.5 I get nothing though. Given the
ability of the AltosDroid App to be able to know where you are as the phone
has its own GPS chipset it does provide a better experience imo for rocket
recovery when compared to using a laptop without GPS. Not to mention
carrying a phone through crop is much easier than lugging a laptop,
especially when I've got a yagi in the other hand! Given this and the fact
that I don't expect to program my EasyMega with AltosDroid I'd ideally like
to revert back to v1.7 of AltosDroid on my Pixel, turn off automatic
application updating for that app, and leave it be. If you could point me
to where I could find that apk I'd greatly appreciate it.

FYI I upgraded one of my windows laptops to AltOS v1.8.6 last night and
promptly upgraded the firmware on my TeleGPS. That worked flawlessly and I
was able to confirm I'm now running the v1.8.6 firmware on my TeleGPS with
the "Configure Altimeter" menu. I then went to upgrade my EasyMega v1.0 to
v1.8.6 firmware. That didn't work. I should have taken a screenshot for you
(and can do tonight) but once I selected the relevant EasyMega v1.0 1.8.6
firmware in C:\Program Files\Altusmetrum\ the application would provide no
further output. I was expecting the small window that confirms serial and
radio configurations and then the firmware installation progress window but
neither appeared. I then attempted to run the "Configure Altimeter" and
whilst the unit still appears as available the identifier for selection had
changed from something along the lines of "EasyMega serial xxxx" to
"Altusmetrum 1" which strikes me as maybe a bootloader ID string. Luckily a
power cycle of the FC allowed it to reboot successfully which was confirmed
by rerunning the "Configure Altimeter" command.  I could see all my
relevant configs, serial, and current firmware (v1.8.5). Just an FYI as it
does appear the EasyMega v1.0 firmware upgrade isn't working in Altos
v1.8.6.

Safe to say I've developed a bit of an appetite for this testing. Today I'm
going to install AltOS on my work Kali laptop (which is Debian based) and
do more testing tonight. Is there anywhere on Linux or Windows where I can
get more granular console output or logging info regarding what's happening
inside AltOS? I don't mind digging through console output if it will assist
in resolving my comms issues. Plus it'll be interesting to see if and how
the comms differ between the different platforms.

Regards,

Andrew H.
