@modaltb 
We also lost all of our calibration, could you send over the backup? 
SN:

Thank you so much.

@tom Hi tom
Thank you, I got those files, Do you happen to have /data/px4/param/parameters_mag.cal too? I'm still missing this one.

@Cai-Bill I do not, but that is quick and easy to calibrate through QGroundControl

@tom also Missing /data/modalai/voxl-imu-server.cal

@Cai-Bill Also easy, just adb on and run `voxl-configure-imu`

Hi Tom,

Someone in our team did the upgrade to our fleet of RB5 without backing up the camera calibration file.
Please could you send us your backup files, and default parameters if possible.
Or the link where to get them if available in Gitlab.

Best wishes,
Massa Ndong

@tahawaru If you can provide me the serial number of your RB5 drone I can do so. It should be located somewhere on the outside of the drone and will be in the form MXX00000XXX 

In order to get all the necessary services running and PX4 params set, I would recommend running `voxl-configure-sku` on your drone and running through the SKU setup, and then after running `voxl-configure-mpa`

Behind the scenes, RB5 shares the same param set as our sentinel drone, those params can be found here: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/blob/master/params/v1.14/platforms/Sentinel_V1.params

@tom 

Many thanks.
Here is what I could find as a serial numbers on 2 Rb5s:
M2300000JDV
M2300000JEE

Do you need all other numbers?
We have 7 of them in the lab.

Best wishes,

@tahawaru Those seem to be the serial numbers of the drone's power modules themselves. There should be a serial number on the plastic outside casing of the RB5

@tom 

okay.

What about these:
M22000007DF
M22000005TW
M22000006H8
M22000005UB

Best wishes,
