Anyone used the iM880B-L?


(Gonzalo Casas) #1

Hi there,

Has anyone already tried this node from IMST? http://webshop.imst.de/radio-modules/im880b-l-long-range-radio-module.html

I’m probably missing something obvious, but I can’t find exactly what’s the programming interface. My assumption is that being LoRaWAN certified, it needs to bundle the stack and be programmable via UART or similar, but the only programmability mention in the docs refers to IMST’s proprietary (MS Windows-only) tool.

Thanks
Gonzalo

Which version did you order:

From their website:

The iM880B-L can be ordered with a pre-programmed embedded protocol stack in two options:
iM880B-L_LR_Base:
This WiMOD LR (Long Range)
Base firmware is a collection of functionalities and applications like
Radio Link Test, Sensor App., Data Link Service, etc. embedded in our
powerful WiMOD OS operating system. It does not include any LoRaWAN
functionalities. The WiMOD LR HCI interface provides to the user direct
access to many radio parameters. Please refer to the download section.
iM880B-L_LoRaWAN:
The LoRaWAN protocol stack, specified by the LoRa Alliance,
is based on IBM’s LMiC and IMST’s WiMOD-OS. It enables Low Power Wide
Area Networks (LPWANs) for Internet-of-Things (IoT) and Machine-to
Machine (M2M) applications and supports Direct or Over The Air (OTA)
activation. It comes with the WiMOD LoRaWAN™ HCI interface and allows
easy configuration. Please refer to the download section.

I haven’t ordered any yet (and there’s also no option to select which version when ordering, but I guess that can be arranged via email).

I did read the snippet you pasted, and honestly, it doesn’t tell me much. What is that WiMOD LoRaWAN™ HCI interface they mention?

Try the downloads section on the page I linked in the previous message…

WiMOD_LoRaWAN_EndNode_Modem_HCI_Spec_V1_7.pdf This document outlines the current version of the WiMOD LoRaWAN™ HCI specification. The WiMOD LoRaWAN™ HCI protocol is designed to expose the radio module services to an external host controller. The communication between host and the radio is based on so called HCI messages which can be sent through a UART interface.

Thank you! I am definitely blind :wink: I was in that download section a couple of times, and every time I failed to notice there was a entire section of more documents below the “General Information” one.

cheers!
