Golioth makes it easy to upload large data payloads from your IoT devices to the cloud. We do this using the blockwise Stream service, which includes a versatile set of transform and destination options so the data goes where you want, in the format that you need. In this post we extend the capabilities of the Blockwise stream to show how async makes a large upload even more reliable over a connection to Golioth.
Golioth released v0.21.0 of the Golioth Firmware SDK, a multiplatform enabler for embedded devices communicating back to the Golioth cloud. This post recaps some of the changes and how it will improve user experience on low power devices.
Golioth allows large data uploads using the Firmware SDK and via blockwise stream calls. This post shows how to modify the Stream sample to try uploading large amounts of arbitrary data and route that data through Golioth Pipelines.
Golioth's Remote Shell uses Remote Procedure Calls (RPCs) and a custom Zephyr shell backend to enable an interactive, web-based shell experience from anywhere in the world.
Golioth released Firmware SDK v0.18.0 which pulls in the recent changes from upstream Zephyr, nRF Connect SDK, and ESP-IDF repositories. We are also introducing new gateway support, adding new supported boards, and improving blockwise transfers.
Sniffing network packets from a cellular modem is actually pretty easy. It only seems daunting because at first glance you're left wondering how to acquire the packets. Nordic's nRF91 modems have a trace capability that can be used to pipe packets from the device into Wireshark over a USB connection. Here's how to use it.
There are a hundred ways to provision a device, and with this NFC-based hack day project there are now 101. Follow along as we us a Nordic nRF53 as a writable NFC tag that parses the NDEF message, locates PSK-ID and PSK, then stores those credentials to add the device to an IoT fleet.
