expo integration

[lucas2xl]

Good afternoon, how are you?

I would like to know if this works with Expo 53.0.9?

I am following this process:

npm install @getquip/expo-nordic-dfu

npx expo prebuild --clean

But I’m getting this error:

⠸ Connecting to: Access Control’s Iphone 15 INFO  BLE::connect(): Connected to device with ID B1DB7E05-DB80-9CDB-35AC-47EC64D104DB.
⠹ Connecting to: Access Control’s Iphone 15 DEBUG  BLE::getChallenge(): Got challenge 3298057390 for device with ID B1DB7E05-DB80-9CDB-35AC-47EC64D104DB.
⠹ Connecting to: Access Control’s Iphone 15 LOG  🔥 Error updating firmware [Error: Error: 302, Error Type: DFUError(rawValue: 302), Message: DFU Service not found]

It seems like the prebuild command did not update my AppDelegate.swift file.

Hello @lucas2xl - it should work with SDK 53. That error comes from the base library here:

https://github.com/NordicSemiconductor/IOS-DFU-Library/blob/43de982ac8bd792c8c72870ac541c2083f7fb7a3/Library/Classes/Implementation/GenericDFU/DFUPeripheral.swift#L371

Are you sure the device you're trying to communicate with has a DFU service?

If you're not sure, I suggest trying out the base library's Swift example app which is available on the Play Store or the Nordic Desktop Tools.

There isn't a reason to have the library update the Podfile or AppDelegate. If the base library shows up at ios/Pods/iOSDFULibrary after you build the expo app, then that should be all you need. That is further evidenced by the fact that you got a log message from the base library in your stdout.

My suggestion is to send send me a repo with a minimum reproducible example. I know I can't test with your specific device, but I can at least tell you if it works with one of our devices.

The Podfile.lock would also show

  - ExpoNordicDfu (1.0.0):
    - ExpoModulesCore
    - iOSDFULibrary (~> 4.15.3)

It worked! Thank you so much; it had been working from the start, and I didn’t even realize it

I'm glad it's going well for you now!
