Cannot Subscribe to Energy/Level and Comm/Peers: A Critical Issue with the Movesense Plugin

The Movesense plugin has been a game-changer for developers looking to integrate sensor data into their applications. With its robust features and seamless integration, it has become a go-to solution for many. However, as with any complex system, there are bound to be issues that arise. In this article, we will delve into a critical issue that has been reported by a developer, where they are unable to subscribe to certain events, specifically the Battery level events and connection notification events for the Movesense MD sensor.

The developer in question has been using version ^2.2.0 of the plugin and has encountered an issue where subscription to certain events looks unavailable. Despite following the YAML specification, which indicates that a subscription route exists for both "/System/Energy/Level" and "/Comm/Ble/Peers", they are unable to subscribe to these events. The developer has tried various combinations of Mds, MdsAsync, subscribe, and post to the "/Subscription" endpoint, both on iOS and Android, but are consistently getting an onSubscriptionError.

Example Code

To illustrate the issue, the developer has provided an example of the code they are using to attempt to subscribe to the "/System/Energy/Level" event:

MdsAsync.subscribe(
  Mds.createSubscriptionUri(serial,"/System/Energy/Level"),
  '{}',
);

This code throws an MdsError, code 404, which suggests that the API routes do not exist. This raises questions about the implementation of the plugin and whether the API routes are indeed missing.

YAML Specification

According to the YAML specification, a subscription route exists for both "/System/Energy/Level" and "/Comm/Ble/Peers". The relevant YAML files can be found at:

The issue reported by the developer is a critical one, as it affects the ability to subscribe to certain events. The YAML specification suggests that the API routes should exist, but the developer's attempts to subscribe to these events have been unsuccessful. This raises questions about the implementation of the plugin and whether the API routes are indeed missing.

Future Implementation

The developer has asked whether the API routes will be implemented in the future. While we cannot provide a definitive answer, we can suggest that the plugin developers may consider implementing these API routes in future updates. In the meantime, developers may need to find alternative solutions to subscribe to these events.

Recommendations

For developers who are experiencing this issue, we recommend the following:

Check the YAML specification to ensure that the API routes exist.
Verify that the code being used to subscribe to the events is correct.
Consider alternative solutions to subscribe to the events, such as using a different API endpoint or implementing a custom solution.

In conclusion, the issue reported by the developer is a critical one that affects the ability to subscribe to certain events. While the YAML specification suggests that the API routes should exist, the developer's attempts to subscribe to these events have been unsuccessful. We recommend that developers check the YAML specification, verify their code, and consider alternative solutions to subscribe to the events.
