Accelerate Your LoRaWAN® Development with LoRa Basics™ Modem-E for LR1121

Introduction to the LoRa Basics™ Modem-E for LR1121

LoRa Basics™ Modem-E v2 for LR1121 marks a pivotal advancement in LoRaWAN® sensor development. Designed with a focus on providing zero-touch LoRaWAN stack integration, this newest release of Modem-E allows the possibility to co-host on the same sensor LoRaWAN and proprietary protocol leveraging state of the art RF performances of LR1121. This will be particularly valuable for customers wishing to offer single SKU devices for multiple LPWAN connectivity options, e.g. SigFox® or Amazon Sidewalk® as well as customers having legacy proprietary protocols and now desiring to bridge toward LoRaWAN yet keeping backward compatibility. 

Moreover, the LoRa Basics Modem-E features an intuitive programming interface through simple APIs, simplifying integration for developers within their existing firmware development workflows. As the IoT market increasingly embraces LoRaWAN technology, the LoRa Basics Modem-E becomes indispensable for streamlining integration process, accelerate time to market, and reduce overall development costs for the next generation of smart applications.   

Whether you are a wireless communication engineer, an IoT developer, or a technology enthusiast, this blog post is tailored for you. We will delve into the history, technical specifications, and compelling value proposition of the LoRa Basics Modem-E for LR1121. 

A Brief History of LoRa Basics Modem-E 

LoRa Basics Modem-E is expertly crafted from the open-source code of LoRa Basics Modem, specifically designed for seamless integration with the LR1121 (LoRa Connect™) chip. This third-generation LoRa chip represents a significant leap forward in LoRaWAN technology, offering an enhanced communication range and an embedded MCU tailored to run a full-featured LoRaWAN stack.  

Semtech® launched the first version of LoRa Basics Modem-E (v.1.x) four years ago, closely linked to the LoRa Edge™ product family and its LoRa Cloud™ services on LR1110. This version was targeting applications requiring geolocation, particularly within asset tracking. 

With the release of this new iteration of Modem-E, we have strategically  

• Removed geolocation capabilities and device management services to focus exclusively on the LoRaWAN stack and  embed all the new features the LoRa Alliance® has introduced into the LoRaWAN specification. 
  
• Added the option to bypass the LoRaWAN stack and drive LR1121 as a mere transceiver that could be exploited to run proprietary protocols on the external MCU in conjunction or in alternative to LoRaWAN.
