Upcoming Webinar: How an MVNO Troubleshoots Cellular Devices

We are hosting a webinar alongside Telenor Connexion on July 2nd, 2025. You can sign up for free here.

Where’s my data? And why is my battery dead?

Golioth is a natural choice for any developer using low power cellular connections to send their data back to the cloud. We operate a CoAP backend / gateway and implemented DTLS ConnectionID to ensure low power operation is possible during your awake and monitoring windows.

But once a packet leaves the cocoon of our hardware products and transits through a tower and up to the wider internet, we don’t always have visibility into everything that is going on.

As it turns out, this is a common problem. We talked with Robert Colvin, IoT Technical Expert at Telenor Connexion. He runs a test lab and helps their customers debug deployments. We walk through how he creates test setups and works through customer problems with a range of capabilities.

What is Telenor Connexion

Telenor is a multi-country MNO that operates throughout Scandinavia and Asia. However, Telenor Connexion is an IoT focused MVNO that operates as a subgroup within the Telenor Group. Their focus on IoT means they can lean on the size of the parent MNO, but develop specific capabilities for IoT focused developers, like SIM localization and specializing in low power deployments.

What you’ll learn

Robert sees a wide range of customer issues and has a wide range of advice as a result. No two troublesome deployments are the same. Here are some of the topics we’ll touch on:

  • The realities of low power modes (eDRX, PSM) on cellular modems
  • Troubleshooting when a tower reports different capabilities than expected
  • How to recreate problematic signals and towers in the lab
  • How can we apply these lessons for our own building
  • The benefits of being able to talk to your SIM (eUICC, SGP.32)

Use the ESP32 AT Binary to Make Any Zephyr Project Wi-Fi Enabled

You can add Wi-Fi to any Zephyr project with an ESP32 running the ESP-AT firmware and a couple of configuration symbols in Zephyr. Let the data flow!

The ESP32 HCI makes any Zephyr board a Bluetooth gateway

Bluetooth HCI enables any chipset to act as a peripheral to a processor running a Bluetooth stack. We pair the ESP32-C3 HCI with a processor running Zephyr to turn Golioth's development platform--the Aludel Elixir--into a Bluetooth gateway.
