My apologies for the confusion. To be precise: we didn't add any third-party or custom heatsink. However, to replace the damaged 4K and ToF camera flex cables, we did have to unscrew the VOXL 2 board from the frame to access the connectors safely.
Once the new cables were plugged in and the board was screwed back into place, the ICM42688 PCB damage / clock line disconnected error appeared.
I have attached the pictures of the current assembly inside our Starling 2 so you can verify that the M0054 board, the integrated cooling plate, and all camera flex cables are correctly in place and undamaged from the outside.
Given the log and the pictures, what do you propose we do to get the drone operational again?
Regards,
Luis

https://forum.modalai.com/topic/1730/bluetooth-ble-communication-on-the-voxl-is-it-possible
I was able to get BLE 5.0 extended advertising scanning working on VOXL2 / Starling 2 with an ASUS BT500 / Realtek RTL8761B USB adapter by backporting newer upstream Linux Bluetooth HCI event parsing logic into the QRB5165 4.19 kernel tree. My understanding is future revisions of VOXL will have more up to date kernels that solve this issue without back porting.
The issue we were hitting was with LE Extended Advertising Reports. With BLE 5.0 beacons transmitting extended advertising, the older 4.19 Bluetooth path could mis-handle extended advertising report parsing / event-type bits, leading to bad report handling and, in our case, Bluetooth instability / crashes during scanning.
The relevant upstream Linux changes I used as reference include:

b48b833f9e8a - Bluetooth: HCI: Use skb_pull_data to parse LE Ext Advertising Report event
ad38e55e1c89 - Bluetooth: hci_event: Ignore reserved bits in LE Extended Adv Report
0cadf8534f2a - Bluetooth: hci_event: Mask data status from LE ext adv reports

There are also related Realtek / extended-scan quirk changes upstream, but for our immediate case the stronger LE extended advertising parser backport was enough to stop the crash path and allow scanning.
Validated result:

VOXL2 / Starling 2
QRB5165 4.19 kernel
ASUS BT500 / RTL8761B USB BLE adapter
BLE 5.0 beacons using extended advertising
btmgmt --index 0 find -l successfully reports devices and RSSI
btmon captures LE Extended Advertising Report events
no more Bluetooth NULL pointer dereference / hci_le_ext_adv_report_evt crash during the test
observed all 16 expected beacons and repeated RSSI samples

I’m not proposing this as a merge-ready ModalAI patch, but I put the build changes and notes here in case anyone else needs BLE 5.0 extended advertising / RSSI collection on VOXL2:

We had a small batch of color AR0144, but those have run out and due to low demand, we do not have any stock.
I would like to clarify something. Motion blur is present when using any camera (global shutter or rolling shutter). Global shutter cameras also have exposure control and long exposure times will cause motion blur.
I think what you may be referring to, which is different in rolling shutter cameras (compared to global shutter), is the rolling shutter skew. Rolling shutter cameras use a technique where the start of exposure of each image row is offset slightly, so each row is essentially exposed over a different time frame. The offset is usually very small (4-30 microseconds per line, depends on the camera, mode), but from top to bottom, the rolling shutter effect can add up and be visible when there are moving features in the scene.
The fastest rolling shutter camera we have right now is IMX412 and in the 2x2 binning mode, the 1920x1080 resolution, the total frame readout time is 4ms. (https://docs.modalai.com/camera-video/low-latency-video-streaming/#camera-pipeline-latency-in-different-operating-modes). This means that the difference of the center of exposure between the first and last image row is 4ms.
Considering the information above, 4ms can seem a lot, but keep in mind that is the time delay across the whole image. depending on the size of features, the rolling shutter effect across a smaller image area will be smaller. Using the height of 1080, we can compute the time offset for each line, 4ms / 1080 ~ 4us.
Depending on the size of features that are being tracked, the rolling shutter may not create a lot of local skew. Additionally, the camera timing is deterministic, so it is possible to calculate the time offset of the center of exposure of each line (with respect to the first line). If you want to provide some more details on type of perception, I could provide more guidance.
Unfortunately, right now, we do not have a color global shutter camera option.
