Arco Naze32 w/Cleanflight won't arm - Please help *SOLVED*

[Revs]

Hi guys, I';m struggling to get the FC on my Trifecta to arm. As far as I can tell I';ve gone through the settings and it looks right.

So far I';ve;
- Installed the latest firmware for the Naze32
- Plugged in the (pre-bound) Spektrum Sat, done the settings in CLI and it';s showing up in the ';Receiver'; tab as working
- Tested the motors in the ';Motors'; tab as working and calibrated the ESCs
- Adjusted the end-points to 1150 low and 1850 high, 1500 mid on the TX (DX8)
- Set the modes in the ';Modes'; tab. Acro, Horizon and Horizon/AutoTune on the 3pos AUX2 switch
- Tried using the AUX1 to arm by setting up the ';Arm'; mode in the ';Modes'; tab

When I switch between modes, the active mode lights up green on the left in the ';Modes'; tab as it should. When I switch to the ';Arm'; pos with AUX1 I don';t get the green box on the left.

When the ';Arm'; option in the ';Modes'; tab is not used and the board should arm with right yaw, that does nothing also.

Can anyone suggest what I might have missed? This is my first go with both the Naze32 and Cleanflight.

Cheers

As it';s your first time have you

Calibrated the ACC
keep the quad level when you try and arm

[Revs]

Ah yes I forgot to mention that. Yes I';ve done the cali on level ground. I noticed that when it';s tilted one of the LEDs lights up, but that goes out when level.

Cheers

In CLI I also did the ';set serial_port_2_scenario = 5'; command as suggested for Spektrum Satellites. As it';s working I assume that';s correct...?

[Revs]

I';ve also read something that suggested I use ';set serial_port_2_scenario = 3'; for Spektrum Serial RX. Not really sure what the scenarios are...

[atomiclama]

what';s the minimum value of the throttle from the rx tab. That needs to go below the
min_check value, not sure of defaults, otherwise it is not seen as a stick command.

CLI stuff from me sorry.

[Revs]

It';s at the default setting which IIRC is 1150/1850/1000. I set the end-points to 1149/1850 on all channels.

[Revs]

Reading further on the port has lead me to believe I may have the ports set wrong. These are the available scenarios..

0   UNUSED
1   MSP, CLI, TELEMETRY, SMARTPORT TELEMETRY, GPS-PASSTHROUGH
2   GPS ONLY
3   RX SERIAL ONLY
4   TELEMETRY ONLY
5   MSP, CLI, GPS-PASSTHROUGH
6   CLI ONLY
7   GPS-PASSTHROUGH ONLY
8   MSP ONLY
9   SMARTPORT TELEMETRY ONLY
10  BLACKBOX ONLY
11  MSP, CLI, BLACKBOX, GPS-PASSTHROUGH

My SpekSat signal wire is connected the pin-4 on the board, but I';m not sure which serial port that is in Cleanflight... port 2..?

[atomiclama]

Soz can';t help you there. I';m on PWM in from the RX.

But you said it was getting values from the RX, well the AUX anyway

One thing the min value 1149 from the TX seems a bit close the 1150

mine bounce all over the place +/- 5us so I have

set min_check = 1040

and get ~1000 from the TX.

That gave me reliable arming.

[Revs]

Yeah I';m getting 6ch';s all working fine. I';ll try increasing the end-point, cheers though the readings are steady, no bounce.

Here';s a short vid for endpoint setup...
Naze32 Quick Tip - Troubleshooting Arming

[Revs]

I think that might well be it buddy, cheers. I';ll have another go on my lunch break.

Say what you want about setting up APM, at least there';s a comprehensive manual in one place. I can find no such thing on Cleanflight just 100 page long threads with scattered info.

Arming issues usually come from

Not increasing the endpoints for throttle & rudder I have mine @ +125% => -125% but some people have gotten away with a smaller increase.

the sticks not being centred (zero in via the transmitters subtrim functions NOT the regular trim switches)

If values jump around you can add a deadband value so the Naze ignores the small value changes (shouldn';t need a value larger than 3)

There is also what timecop charming called moron_threshold which can prevent arming if the machine is moved while the gyros are calibrating after power up (happened to me when I powered the 250 up while it was sitting on the car boot)

[Revs]

Limits set to 1095-1905 all round and it arms fine Just had a little fly!

Thanks for the help, guys. Much appreciated. I';ll get some vids up this weekend all being well
