RSSI (PWM) and CPPM output - If CH3 and CH4 are connected by a jumper, CH1 will output CPPM for CH1~CH8, and CH2 will output RSSI (PWM)

The XP shows that it has this where the II does not.

They're of use for multicopters, OSD's, autopilots and the like. CPPM = all servo channels on one pin, RSSI = receiver's radio signal level indication.

If you don't know what they are you probably don't need them ;)

Does anyone know where there are instructions posted for flashing a D8R-II+ with XP firmware?

And is FrSky's FrUSB-3 (FUC-3) cable required (http://www.foxtechfpv.com/fuc3-frsky-up ... p-630.html), or is it possible to use FTDI or something?

D8R-XP firmware hasn't been published, so we don't have a file to flash (there is one around, but it was a beta and it has non-functioning RSSI output).
You need a converter with RS232 levels, not TTL like most common USB->serial cables used for that kind of gear. The frsky cables are pretty much the cheapest ready-made ones around.

does the XP FW have all the function/capability that II+ has with additional capability of cppm and rssi?
if so , I certainly am waiting for the new FW release so I can convert II+ to XP.
I got the II+ by mistake. ;)

also, isn't there is a way to dump the FW from a XP to load in II+? or there is hardware difference too?

Kilrah: thank you for the detailed reply. I'll definitely be picking up a FrSky FUC-3 :)

kaos: I'd love to get the XP instead, but damn Hobbykock only has the DJT combo with the II+ or V8FR-II.

Yep

Unfortunately not, their devices are read-protected. Hardware is the same. But a firmware upgrade for the XP will be released soon, so we'll certainly have a file.

as far as I know the receiver will have to be flashed as well.. that is what I understood from following the PXX thread here.. If I'm wrong I do apologise..

Joao

EDIT: I guess that in case we would have model match and bi-directional communication between module and receiver, it would be necessary to upgrade the receiver as well..
Just me thinking, which doesn't happen very often.. :D

With the current PXX implementation, only the Tx module needs to be updated.

An I am for a change - not clueless!

Pace of development/change is crazy! I have been pre-occupied with paying work for a few months; and now I have to relearn everything :-)

The latest D8R-XP firmware has been posted on FrSky's website > http://www.frsky-rc.com/download.asp?id=23

Can anyony confirm whether or not this will fully work on the D8R-II; outputting both a 8channel 27ms CPPM and RSSI signal?

Comment off diydrones..
R_Lefebvre: "I asked them about the older receivers, and they basically said that maybe you could put the firmware for the D8R-XP into a D8R-II, but they don't recommend it and don't know what will happen." (http://www.diydrones.com/profiles/blogs ... m_blogpost)

Is the hardware of the D8R-II and D8R-XP the same? If so, is the only difference between the models the firmware?

Because is fleshable by XP yes and behave as XP after flash even leds signals are as XP....
Not the first company that make new package and new sw and have new product but in this case is ok because II+ had no hw errors and works well...

Not that it's really too important, but I know the D8R-II+ has a hard case and I hear the XP has a soft case. ? I don't have an XP.. I'm fine with the II+'s I have so far.

XP does have a hard case too. they have identical case with different color labeling, even the case color is the same. (At least for mine)

Can someone confirm the beta release FW to upgrade II+ to Xp is working properly and ready to be used?
If so, I am going to flash my II+ to XP. ;) with RSSI/TSSI CPPM available, it has so much more usage.
