HI guys.
had to go for an Seek pro IOS socalled new at 290USD even though we didnt had any IOS-equipment with Lightning-plug, but instead numerous Android devices with Micro USB.
Reached out to Seek Thermal, and obviously not something they have many interests in answering, in regards using their products on different platforms then intended, they did state that in theory, it could work as not much hardware differences if any, its usually the other way around there are issues, using Android devices on Apple IOS as there are some minor hardware differences here...

Has anybody here experienced with an IOS Seek Thermal on other systems then IOS or can a person just "plug and play" with basic china-adapters Lightning 8pin to Micro USB usually 4 or 5 pins without any deeper pinout guidance beforehand.?

>  All these el'cheapo lightning-adapters have finally arrived from the slow boat from China and I'm an a little hesitate to just chance it with a relative delicate sensor-equipment, after all I did end up going for an Ipad2018 in the long waiting time so do got a native system to use it with https://www.youtube.com/channel/UCTJtb7oyUVo0CVfd0RQ5rsw?
but still would be nice to be able to use it also with ones Android-phone.
Are there any specific risks too have in mind or problems triggering the OTG protocol, when using 8pin Lightning to 4/5pin MicroUSB adapters or anybody here used their IOS Seek Thermal on other systems then native IOS fx with Android or perhaps Windows OS true thirdparty software.? Or will it be a problem trigging the OTG standard

// Hmm, been trying with different mobile-fans, and it seems like the OTG standard gone lost in translations between 8pin Lightning to Micro USB or TypeC so no power is drawn.

I would be very surprised if any of these adapter works ...
You'd better sell it, and buy one for android !

As noted in the text and with links to my footage on IOS, its not a mistake I decided to purchase IOS so any reason for sell, is of course out the door.
It performs brilliantly from a 230 EUro pricepoint on my Ipad2018 and love the footage it performs with decent framerate..


But as noted it would also be a gain if it was open for use with one's Android-phone or windows for that matter.
It was mainly in regards to issues with using IOS device on Android as long as you got an lightning to Micro USB adapter with the correct pinout.
The main issue seems to be the OTG protocol (getting power) their aint seem to be triggered.

From my old ticket.

Hello Hviid Holding,

The Seek Compact imagers are not designed to work with the opposite platform, even with the use of an adapter. There are slight hardware differences between the cameras for iOS and those for Android. The Android cameras lack a component necessary to run on an iOS device. It is theoretically possible that an iOS camera could work on an Android device, but Apple doesn't authorize the necessary adapter and we do not test against that scenario.

Some industrious customers may have been successful, but we haven't seen or heard any reports that suggest it will work.

From memory, the significant difference between iOS and Android versions of phone based thermal cameras is the Apple ID chip that sits in the USB path. This chip is licenced by Apple to identify the accessory as a valid unit for use with Apple products. This is why Android accessories will be rejected by an Apple host as incompatible. In order to use an Apple version of an accessory on an Android platform, I believe you will need to bypass the Apple ID chip inside the camera. I recall someone attaching a USB cable to the camera side of the Apple ID chip and it apparently worked fine as an Android SEEK.

Of course, any attempt to do such a modification is totally at your own risk and you need steady hands and skills to work on these compact cameras. I suggest you do some research on the Apple ID chip, how it works and how it is connected into the USB/Lightning path.

The ID chip was first noted when Lightning was released.......

https://bits.blogs.nytimes.com/2013/02/14/lightning-apple/

Apple treat details of the ID chip as Corporate Confidential, so it is hard to find details of its implementation but some Googling may turn something up for you. I do not know whether it sits across the USB data and power lines, or in series with them. as such I do not know how it interacts with the accessory USB port or the host.

The device can not be detected by Android or PC if you use the lighting to micro usb adapter.
however ,the key is not the "chip" but the definition of the lighting connector.
the micro usb connector on the Seek is Vcc D+ D- GND,but the lighting connector on the Seek is Sb D+ D- GND.the pin Sb provides 5V only when IOS detect that is an OTG device.
if you do not want to disassemble your Seek ,you can just connect the pin 4 on the adapter to Vcc
this pic may help you:

As you can see, I did not "connect the pin 4 on the adapter to Vcc",I just soldering directly on the FPC.
The red wire on the back side and that is connected to pin Sb.
Do this at your own risk :)

so someone has to make a specific adapter ( but it's doable) .


and it would surely not work from the other side, buying the android device and use it (wit hany adapter) on an ios device.

This looks similar to the ID chip system that Apple have now employed on their USB to Lightning cables. The data lines and 0V are not interfered with, but the chip sits in series with the power rail. Thank you for confirming the SEEK iOS interface design.

Regarding an android device running on an iOS device using an adapter cable..... Apple want to prevent this so the Apple ID chip (or a clone of it) must be present and correct for the iOS device to interact with the device plugged into the Lightning port.

The Apple ID chip is a Texas Instruments BQ2025. Undocumented, under NDA, but the parts around it(24, 26) use the TI-developed SDQ single-wire interface. Inside is just a gate array that does an improperly implemented challenge-response communication sequence.

More here: https://www.chipworks.com/ja/node/98


Just solder directly to the USB lines and ignore the TI chip, it should still function as a normal USB device without it.

I changed the adapters. The version under ios worked with android.

how can you get an adapter as a spare part (without buying a complete unit ...) ?

I was given a few not working thermal imagers. About a third of failures can not be repaired (sensor array malfunction, damage to internal layers of conductors in the electronic board). For testing, you can solder the micro USB to the contacts on the board.

Hi, has anyone attempted making such an adapter? Thinking about making one for Seek iOS converting it to USB-C.

I got a couple of lightening extension cords on Amazon (links below) and verified all of them work fine with Seek. Now I just need to figure out how to connect the female end to a USB-C male plug.
https://www.amazon.com/gp/product/B07TCYQP98/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
https://www.amazon.com/gp/product/B07ZJ13Z8L/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1

@tonykids, thanks for the info you posted a while back.
So what you were saying is that, taking the lightening port receptacle view below with pin #1 being GND, so you were saying I need to feed both pin #4 & #5 with ACC 5V, is that so?

[8 7 6 5 4 3 2 1] (receptacle view)

I'm very new when it comes to lightening port. When the device (iphone) is charging, I measured pin #5 at 5V.

However when Seek is connected working, I measured pin #5 at 0V (very strange...), pin #8 at 3.3V and pin #4 at 2.97V. I'm afraid that the camera might burn up if feeding 5V to pin #4 and/or pin #5. Also what about pin #8? Any comments?

Thanks in advance!!!

I have both an iOS and Android version of the Seek Compact and was also trying to figure out a way to be able to use only one type between both platforms.

I purchased a Lightning Female to MicroUSB Male adapter on eBay :
https://www.ebay.ca/itm/8-pin-Lightning-to-Micro-USB-Socket-Converter-Adapter-Connector-Date-Charge-US/153499011862

I then carefully cut the side of the aluminum housing, pried it open and removed the moulded internal assembly, which I also had to carefully slice open on the side edge using a sharp knife. See the photo below.

I took photos and made a schematic. Per information in this thread, I jumpered MicroUSB pins 4 & 5 to enable USB OTG when plugged into an Android device.
I then jumpered pins 4 & 5 on the Lightning connector to allow continuous power to any device plugged into that socket.

My Seek Compact is now recognised by both my iPhone AND my Android phone and I can use it pointing forward or backwards on either device.

NOTE: I take no responsibility for anyone doing this modification as I have no idea how it will affect the devices it will be used with.
It works for me.
YMMV

Regards,
Larry

Hi Larry,

Just brilliant!!!

I followed your instructions and got my CompactXR iOS version to work on a Samsung S7. I happened to have a female lightening to micro USB converter with me, exactly the same as yours.

Somehow it didn't work first for me after the soldering, and I had to wiggle the connectors a bit to get the camera to register in the app (which might explain why my previous attempt had failed), after that it was all smooth.

Thank you so much for sharing this!  :-+ :-+ :-+
