could not connect to the Noe Pen I Bought (NWP-F121).
Unable to connect to Pen in Sample app on GitHub, and Neo Notes on app store.

Hi,

Pen model NWP-F110 is not storing offline data. I have disconnected the pen from the phone, and stopped the app from running. Neither my implementation of the SDK nor the sample app see the strokes. The pen memory says 0, as if it's not saving it.

Is there some way for me to turn on offline sync mode on the pen? The documentation says it's turned on when the pen is first connected but it doesn't appear to be.

I am experiencing an issue where lighter strokes are clearly visible on paper but are not recognized by the SDK. Only when I press the pen down harder I get stroke data.

Is there a way to change the sensitivity using the penPressure state? What range of values does - (void)setPenStateWithPenPressure:(UInt16)penPressure; accept and what do they mean?

I was also wondering what exactly some of the other pen state properties do, especially useAccelerator and useHover. I use an F110 by the way, so the SDK is version 1.

typedef struct __attribute__((packed)){
    int32_t timezoneOffset;
    UInt64 timeTick;
    UInt32 colorState;
    unsigned char usePenTipOnOff;
    unsigned char useAccelerator;
    unsigned char useHover;
    unsigned char beepOnOff;
    UInt16 autoPwrOnTime;
    UInt16 penPressure;
    unsigned char reserved[16];
} SetPenStateStruct;

It appears that Apple requires MFi Program authorisation before I can submit my application which integrates with Neo smart pen to App Store.

The app submitted is otherwise rejected with following message

"MFi - Program Authorization

We are unable to post your app to the App Store at this time because your app has not been authorized by the accessory manufacturer to work with the MFi accessory.

Next Steps

To resolve this issue, please contact the accessory manufacturer to request your app be added to the MFi Product Plan form.

Once the accessory manufacturer confirms that your app has been added to the MFi Product Plan form, please reply to this message. When we receive your reply with this confirmation, we can proceed with the review; we do not require a new binary even though your app's status in iTunes Connect is Rejected.

If you have not yet provided the accessory's MFi Product Plan ID (PPID), please enter this information in the Notes section for your app in iTunes Connect. If you do not know the PPID, please request this information from the accessory manufacturer."

Please advise on how to required authorisation.

Thanks

Will this sdk work with the dimo pen? Is there any plans to release an sdk that works with the dimo pen?

Hello,
I have just looked into the sdk. so far observed stroke data coming from pen.
What is exactly the origin of this stroke data on A4 paper? is that the left top corner of paper? or any offset?
What is the unit of stroke data, is it cm? mm?

Thank you for your reply.

Great to see open SDKs for the NeoSmartpen!

I'm trying to port the SDK to macOS. For now I have simply omitted the functionality that uses UIKit - the only iOS-only dependency.
Connecting to the pen seems to work just fine, I don't get live stroke data though the callback doesn't fire at all.

Am I doing something wrong? Or maybe this isn't viable at all?
Have a look at my code here: https://github.com/StudioProcess/NeoSmartpenMac

Hi,

SDK 2.0 is giving only 2 services for new pens which are as follows:
1> 19F1 - NEO_PEN2_SERVICE_UUID
2> 180A - NEO_DEVICE_INFO_SERVICE_UUID

I am not getting any other services (like, 18F3 - NEO_OFFLINE2_SERVICE_UUID) while connecting with pen via bluetooth.

Old pens are working great with new SDK 2.0, but having trouble with new pens.

I want to use offline data delegate for retrieving offline data from new pens, but its not working even in your sample app also.

Kindly give your inputs asap.

I can't seem to get ProcessStroke to get called in swift. I made sure I set the stroke handler to self and have almost line for line matched the Obj-C version of the project.

whenever I run btStart it returns

Any interest in distributing this project as a cocoapod? Or by some other means?

The framework you've directly committed to source control is out of date, and I had to fix the project build in order to get the latest framework which is not ideal.
