@jberi will I be able to connect the Xenon device to a phone as a peripheral over BLE?
We talked here about which Bluetooth features we plan to include when we ship and what we hope to add over time. But to quote myself :
We generally try to be thoughtful about which features we add to our Device OS because more features means more flash and RAM used by the system and less resources available to your application. Since the primary role of Bluetooth in Particle Mesh is for device setup and diagnostics, we don’t plan to support generalized and broad Bluetooth functionality when we ship…In the fullness of time, we’d like to add API support for Bluetooth. However, we will be focusing our efforts for the initial release on the primary use case of device setup and diagnostics over Bluetooth. We have other ideas on how we can leverage Bluetooth that will also not be included at launch.
What use case do you have in mind that would use the BLE Peripheral role?
Thanks for the response!
I just want to connect to a custom mobile app (Android and iOS) and send commands to the Particle device using just bluetooth similar to Spark.function(“funcName”, funcName);
This is also what I need. I got 10 pieces, but they are useless without this feature. The Mesh connectivity will be grandios but it should be initiated by a Smartphone and also without network connectivity.
Updating can be then made using an Argon or Boron.
Same. Without being able to connect a custom app to the device then the device is useless. Transparent UART is fine, if there were hooks in firmware to call functions with parameters then that’s even better.
Just semantics, but that may be true for your use cases, but that doesn’t make the device in itself useless.
However, it was said often enough I think that is a top priority feature that will come as soon core features and stability are allowing for moving on to implement it.
True. I’m sure there is some industrial use case that this whole mesh journey started on as a cornerstone client.
I waited 18 months for BT to be added to Particle. I used a microchip RN4870 BT module as a stop gap, but that costs an extra $10 per unit on top of a P1 that cost another $10 and overall doesn’t have the range of BT hub features I want to deploy. My competition meanwhile built a new generation on ESP32 and are doing very well.
So now I’m halfway through a project with devs in Ireland to build me an ESP32 with the appropriate services. On ESP32 the BT stack chews a lot of memory but still has room for MQTT client and server (ie not only can it push events but can be controlled via MQTT from a smart phone app as though it was a serial device. very cool). There have been a number of issues identified by a couple companies I know but at least those issues now have solutions.
Just wanted to highlight this branch in case you’re keen to get it working before it’s officially available (read: possibly lots of pitfalls for now):
