FYI: Just got a notice from Digikey about this new offering from MC

It has a M4808 + wifi and provides usb charging of lipo battery (not included)

MC part # AC164160

DK part # AC164160-ND price $29.87 and shows 191 in stock

 

Looks like a fun way to learn about the new AVR+0 chips

No programmer required, simple USB file drag and drop programming, also has console access via usb com port.

Getting Started with AVR-IoT: Pushing Data from Device to Cloud

by Eric Zhang (Leverage, systems engineer)

October 23, 2018

https://www.leverege.com/blogpost/avr-iot-guide-pushing-data-to-cloud

...

Our team at Leverege collaborated with Microchip and Google to simplify this process by making AVR-IoT an out-of-the-box experience for engineers and developers. [AVR-IoT has] a pre-configured connection to a sandbox on Google Cloud.

...

... you can re-create the sandbox interfaces on your personal account. 

...

[GCP - Google Cloud Platform]

...

[how to with YouTube videos]

...

[Atmel Studio though implies that MPLAB X may be next]

...

If you’re looking to build something bigger, our team can help you scale your projects into full-blown solutions.

Having WiFi defines it as an IoT thing? Oh, well, I looked up some "references" that include both WiFi and BT as "IoT technologies".

 

I would have expected support for SigFox, or LoRa or LPWA or 6LoWPAN or Thread, or something like that.

Bluetooth 5 as that adds mesh networking.

Microchip's Bluetooth 5 industrial temperature range modules aren't extendable though are configurable (discrete IO, UART) (UART is transparent, iow "wireless" cable)
Nordic's Bluetooth 5 SoC is extendable and has a SDK for 6LoWPAN and router software to bridge to WLAN.

The other Bluetooth 5 manufacturers likely also have such an SDK or equivalent.

SigFox - mostly Europe?

LoRa - apparently has some traction in the US (network service by third parties)

LPWA - Digi-Key has low power cellular packages (modems, gateways, SIMs)

6LoWPAN - in Android so could use that OS to bridge to WLAN

Thread - does Thread need a gateway?

Thanks g for the into's, I have a lot to learn with these!

Press Release

Accelerate Development of Remote IoT Nodes with the Industry’s Lowest-power LoRa System-in-Package Family

With industry-leading low power consumption, the SAM R34/35 devices enable long-range wireless connectivity while extending system battery life

Munich, Germany

November 13, 2018

https://www.microchip.com/en/pressreleasepage/industrys-lowest-power-LoRa-system-in-package-family

...

The SAM R34/35 SiPs come with certified reference designs and proven interoperability with major LoRaWAN™ gateway and network providers, significantly simplifying the entire development process with hardware, software and support. 

...

Highly integrated in a compact 6 x 6 mm package [BGA-64, 0.65mm pitch], the SAM R34/35 family is ideal for a broad array of long-range, low-power IoT applications that require small form factor designs and multiple years of battery life.

...

According to the LoRa Alliance™, the number of LoRaWAN operators has doubled from 40 to 80 over the last 12 months, with more than 100 countries actively developing LoRaWAN networks.

 The problem is that the term IoT is totally marketish, thus it is vague and informal. People say IoT and assume M2M, which has been there for decades now. It runs over 3G and feels just fine, thank you. For this type of communication BT is overengineered (well, it just is so, no matter of application), WiFi is too fast. LoRa is deveoloped to replace 3G-based M2M. Nevertheless, both BT and WiFi are excellent for transition period because they are well known and used globally.

 I see no point in 802.15-style meshes at all. Too complex to control a bulb and a pump in a household, too slow for multimedia streams. Why, then?

[Edit]: from technical point of view, only WiFi and LoRa are worth attention. Alas, BT and others won't excinct any soon. It's like Intel and Windows: no one likes it but everyone uses it.

Update: my package arrived from digikey, hope to find some time over the up coming holiday to play with it and report back, but don't hold your breath!

 I will, anyway, because I've just finished porting WINC1500 ASF driver to 324PB. Would be nice if you could share some energy consumption measurements.

It is still way too complicated. How do I connect my own sensors to the cloud? How do I connect my own assembler programs with the offered cloud functionality?

It's nice if a 'out of the box' cloud connection is demonstrated. But if you just want to use this functionality without having to deal with all internal details? If you deviate from the given inflexible rigid line, it quickly becomes very complex. Since it helps nothing if the word "easy" is used inflationary.

Too many such boards are already on the market and dust after the first try.

Too often, these are technological feasibility studies without any thought as to how to use innovative features like cloud functionality in really every situation, simply usable from every position. There is much more to simplify.

How about an encapsulated cloud interface, configurable via WLAN and with UART. There is only a specific number with associated reading transferred. How the measured value is then evaluated, displayed and archived can be determined on the Internet at the cloud provider. That would be a simple, universally applicable cloud solution. No unnecessary work with any protocols, transmission and security details etc.
