July 28, 2011

-
Thanks for the heads up! We've pushed an update to the GitHub repo -- updating the board definition file. Should resolve those issues and get you up-and-running with SDK 1.4.0.
-
Thanks! Gotta love those breaking changes :S
I pushed an update to the GitHub repo which should enact similar fixes. It's working well with SDK 1.4.0.
-
As the RedBoard doesn't have a unique USB VID/PID (just uses the standard FTDI ID's), I'm not sure the board manager will be able to find it.
I was using a RedBoard during the duration of writing this tutorial, though. You should be able to use an Arduino Uno (
arduino:avr:uno) as a substitute for it. -
Great question! The cables are oddly hard to find... This has worked for me.
-
I've pushed some updates to the GitHub repo -- it should make all examples compatible with v1.3.11 of the SDK.
-
Thanks for the heads up 134773! We'll definitely get more links to Hologram.
They've got a really maker-friendly service: cool prototyping features like TCP/UDP messaging and webhook-routing. And it's pretty cost-efficient if you're not sending too much data.
-
You're right that its getting a lot easier to get data-only plans. Yay! You can get the shield without an included SIM over here and use any plan that supports Cat M1 or NB-IoT.
Why Hologram? Their service supports most carriers, including AT&T, Verizon, and T-Mobile. They've got a cool set of included features: a convenient dashboard to monitor data usage and messages, a bi-directional TCP- or UDP-based cloud messaging service, and handy IoT webhooks to route that data -- those help a lot during prototyping. Plus, their pricing is straightforward.
-
Unfortunately not, the only examples in the SDK are a distance detector, and how-to's on using the IQ, power bin, and envelope services. Hopefully Acconeer continues building on the SDK to produce more application-esque examples.
-
Thanks for the heads up. I updated the installing instructions here a bit too.
I uninstalled and reinstalled, and it seems to be working for me (following the Windows directions). Make sure you've installed the core in your Arduino sketchbook - exactly as specified. The "esp32" folder should reside in "{Sketchbook Location}/hardware/espressif/".
-
Not easily, unfortunately. Unlike a lot of I2C chips, the BQ27441 doesn't have an address-select pin or otherwise configurable I2C address. In lieu of separate I2C buses you could use an I2C multiplexer (for example) between a microcontroller and the pair of BQ27441's.
No public wish lists :(
