Tester vs Programmer

Content As of my last knowledge update in September 2021, the Web Bluetooth API does not provide a built-in mechanism to automatically retrieve a list of all available services on a Bluetooth device. You typically need to know the UUIDs of the services you want to access in advance. However, if you're in a testing or debugging scenario and you want to discover all available services on a Bluetooth device, you can do so manually by iterating through all possible UUIDs. This is not a recommended approach for production use, but it can be useful for testing and exploration. Here's a JavaScript example of how you can iterate through a range of possible UUIDs to discover services on a Bluetooth device: javascript Copy code async function discoverAlIServices (device) ( const discoveredServices J; Generate a range of UUIDs to test (e.g., 00000000-0000-0000-0000-000000 for (let i 0; i OxFFFFFFFFFFFFFFFFFFFFFFFFFFFF; i) const wuid i.toString(16) .padStart (32, 'O'); try const service await device.gatt.getPrimaryService (uuid); discoveredServices.push (service); catch (error) I Service not found with this UUID, continue searching return discoveredServices; C Regenerate

CSS error javascript web C java code node.js 19th January 2020, 11:37 AM Ambitious Coder 5 Answers NEW ANSWER Sort by: Votes 4 Compilers's errors or warning aren't there for nothing. They are here to tell you that something went wrong on a specific line. Even if it knows what's the mistake, it isn't his job to correct it. Else, it would create even more errors, because it doesn't know in which way you've implementing your solution. Imagine a compiler saying : 'Error, print is not defined, did you mean printf' then the compiler replace print with print. In fact, you really want to call a function named print, but you forgot including the right header. Then, all vour code is false and vou have to correct the compiler's correction manuallv : that's not worth!
