Devo RPM Sensor Doesn't Seem To Work...

[WalkeraHelicopterSupply]

From a customer:

I have a Devo 10 Transmitter with Software Ver. 0.6A and Library Ver. 0.2, I am using it with an RX 1002 receiver and a WK-CTL01-D Telemeter module.

I use 2 Temp sensors and 2 voltage sensors and they all work very well.

I also have the WK-MP.PM RPM sensor but I can not get any RPM readings on the transmitter. I see the RPM indicator in the “Sensor View” mode, but it is always 0. I have the sensor magnet well within the recommended 2mm from the sensor.

I notice in the “Sensor Setting” menu there are “Voltage, Temperature, and GPS” settings but no RPM setting, yet there is RPM in the “Sensor View”. Is there a compatibility issue with the Devo 10 getting RPM readings, and how can I fix it?

Devo10 can display RPM information, he said he see the RPM indicator in the " Sensor View" mode, but it is always 0. the problem is he didn't set up it in right way. he should put RPM on something vertically which he want to test it, attached pics for your reference (just take gear for excample, dont' care).

Voltage, Temperature, and GPS have settings, don't need to set RPM.

Hi Dave,

The RPM sensor is now working.

The key is the magnet must be within 2mm from the face of the sensor; I had it to the side of the sensor. The Hall effect sensor is the small cube at the edge of the circuit board and apparently only senses the magnet on it’s bottom side.

I also finally got a response directly from someone named Lily at Walkera, so between the two e-mails I was able to figure out what they were talking about.

As I’m sure you know Walkera makes great products but their manuals and instructions are, (being kind) difficult to understand.
