I want to go back to Lost packet indicator rssi, with the lastest upgrade (12ch ppm mode, etc...) Sid made to the firmware. If you are happy with RF RSSI, good for you. I am not and want to go back without loosing 12ch ppm. |

Thank you Sid,
My RangeLink arrived on Friday here at home, took 15 days and everything arrived as agreed. I tested the system on the ground and everything ok. In the first attempt, I connected only the positive wire ( center pin ) on EagleTree and the RSSI indication was only 1% is with the radio on or off (already done the calibration on OSD) I noticed with a multimeter that the positive wire was 4.7V and the signal wire was 3.3V. So, for the RSSI function properly in my EagleTree I needed just connect the signal wire (but in the middle pin) on Temp1 at E-Logger and to principle worked great. Tomorrow if the weather permits I will test in flight. |

Hey, relax.
All I was trying to say is that this sentence does not make sense "I want to go back to Lost packet indicator rssi" It is two separate things. Quote:

It's not progressive in the slightest. When I range tested original firmware out to 30 miles, any time I had good LoS, it pretty much showed 100%, and when the signal degraded, it'd often just drop right to zero. It rarely spent much time in between. Rf RSSI over the same test route goes down progressively (not necessarily linearly), so I could easily judge when I was approaching edge of range, or see when it was affected by external Rfi, quantify the effects of antenna orientation, positioning, and so forth. ian |

), but in some situations is preferable. With RF rssi it senses every signal on 433 mhz, not just your tx. It's not very useful for me, first of all because I can't really calibrate the rssi gauge. When I power down my RLtx (failsafe) it shows every other signal on the band (sometimes 10% or less, sometimes even 40-50% strenght). I tried to calibrate it in less rf polluted area, at longer distances, and even in flight, but I am not satisfied with it, because I should recalibrate in every place I fly, and even when I do, I get failsafe sometimes at 70%,sometimes at 30%, etc...really unpredictable. I fly in very different places with very different aircrafts: in the mountains with a glider, far from every disturbance, I am sure rf rssi will be much better and the real range will be more predictable, but near urban areas or at my usual flying field (with an heli or a multirotor) it's not, and I just want to be able to use lost packet indicator (with 12ch ppm mode of the latest firmware upgrade). The key to understand my request (Bingo 17 didn't get it) is the last part of the sentence: "with 12ch ppm mode of the latest firmware upgrade". ![]() Anyway, I usually fly well below the max range, I don't really like going so many miles away just to prove it can be done. |
