BluetoothLEServer "Samples" aren't broadcasting the BLE server.

[bwinklesky]

After flashing with the ESP32_BLE_REV3, I tried setting up the BLE server using the sample code (Sample1 and Sample2) my scanning app doesn't find it Sample1 or Sample2.

What am I missing?

I beleive I found the answer in the JsonConfigurationStore sample. I assume "I:" is the drive letter for the internal storage?

[josesimoes]

Yes, I: is the internal storage drive.

The Storage samples, which you seem to have found should point you in the correct direction. Any C# code sample with the FileSystem API can also help you.
As for the exception, if you explain what exception you're seeing and the code that is throwing it, would be helpful to help you. Otherwise this is a wild guess....

The exception was from the "D:" and "E:" drive not being mounted. Unfortunately, I didn't expand the Init region when running the code in Visual Studio and didn't notice the section you pointed out on line 38. Maybe you can move those comments above the variables?

There drive letter is cast in stone (you cannot change it in nF). For internal storage it is always i: drive. The others depending on the type of storage and not all types are support on every MCU.

 // D: is SD Card
 // E: is USB drive
 // I: is Internal flash drive

I don't anticipate needing to mount external storage, but this is good to know!

For Json data, has anything for casing implemented? We use camalCasing for our API service and set the options when serializing.

[josesimoes]

Yes, there is. Mentioned in the README:
https://github.com/nanoframework/nanoFramework.Json?tab=readme-ov-file#case-insensitive-members-resolving

[bwinklesky]

Sorry, my question wasn't clear. Is there a way to serialize pascal case to camel case? Or is the best practice to define the members of a class in the appropriate casing?

[alberk8]

I guess the easiest way is to define the class members in the expected case.

One more question...

When deploying to ESP32, it gets hung up on something when writing to the flash and I need to hit the reset button to get it to deploy. Is this normal?

[alberk8]

yes, especially when BLE is in Peripheral Mode (receiving connection from other BLE Central).
