No itās not a Girlā¦ But a technology that is becoming more popular.
the information about LoRa devices, LoRaWAN protocol can be found in several official resources:
Semtechās Official LoRa Documentation (Semtech is the creator of LoRa technology)
As much as the Tracker 1000-E has been bashedā¦ i think it is one of the most successful plug and play seeed devices I have had the pleasure of working withā¦ The software support is at the mercy of Meshtasticā¦ but I am actually plesently surprisedā¦ especially because i had bad ego interactions with them on the discordā¦
this device ā¦ unfortunatly is a low performerā¦ only for prototyping, stronger for LoRa sensors in close rangeā¦ maybe 100 yards max and direct line of siteā¦ but it also is supported and performs on the meshtastic networkā¦ just GPS and LoRa range is weak. works flawlessly with LoRaWAN gateway and Seeed Dashboard. Totally a proff of concept device. i hope it could be upgradedā¦ because i love the 6 grove ports!
Relying to this topic because I canāt seem to figure out how to create a new topic!?
I want to use the Wio-SX1262 Module in a project so I can leverage the module FCC certification but looking at the FCC approval it has three antennas an FPC, Spring and Diapole. It doesnāt look like you all sell the FPC antenna that was used and the 2 dBi external antenna and SMA to I-PEX antenna cable one you do sell is not in the FCC approval. Am I missing something? I would like to buy a few modules with FCC approved FPC antennas. Thanks for any thoughts!
Adding to the post based on PJ_Glasso (thanks for replying!)ā¦
I am looking at the Wio-SX1262 with IPEX antenna connector for US market. I have a base that is powered and would like to put a 2 dBi external antenna like the one you all sell (External Antenna 868-915MHZ-2dBi;SMA-L195mm-Foldable) and then use the FPC antenna for the remote units (But I donāt see you offering this antenna). I looked at the FCC report for the Z4T-WIO-SX1262 and it has three antennas but they donāt really align with what you all sell except for the outdoor dipole. Is there someone that could provide some clarity on the situation, the goal would be to buy a FCC certified module and antenna based solution and then just do a certificate of conformity for the remaining simple circuit (I am definitely out of my depth on the FCC stuff but seemed to have read enough to feel somewhat comfortable with the options).

What is the Difference? LoRa is the radio modulation technology ā it defines how data is physically transmitted over the air using long-range, low-power signals. Think of it like the ālanguageā the radios speak.
LoRaWAN is the network protocol that runs on top of LoRa ā it defines how devices identify themselves, join a network, encrypt messages, and communicate via gateways to a network server. Itās the ārules and infrastructureā for a LoRa-based IoT network.
If LoRa is like āMorse code,ā LoRaWAN is the postal system that figures out where each message goes, ensures delivery, and handles security.
LoRa ā Just the long-range, low-power radio modulation (no rules, no network).
LoRaWAN ā Adds the standardized network protocol, encryption, and gateway/cloud infrastructure for IoT devices.
Meshtastic ā A custom, open-source firmware for LoRa radios that turns them into a self-contained mesh network ā no gateways, no internet required ā devices relay messages for each other peer-to-peer over LoRa.
If LoRaWAN is like mailing letters through a postal service, Meshtastic is like passing notes through a chain of friends until it reaches the person you want.
LoRaWan has so many interesting possibilities. I played with raw LORA and did not have fun handling half duplex coms myself. I should have just gone straight to working with LoRaWan!
LoRa is not a person but a wireless communication technology developed by Semtech. It focuses on long-range, low-power communication, making it ideal for IoT devices like sensors and trackers. While LoRa defines how data is transmitted over the air, LoRaWAN is the protocol that sets the rules for networking, security, and communication between devices and gateways. Together, they enable reliable, low-power, wide-area communication.
To get started, beginners often experiment with SX1262 or SX1276 modules and simple libraries like RadioLib on Arduino or ESP32. This lets you send and receive data between two nodes before moving on to LoRaWAN networks. Once comfortable, you can connect to public networks like The Things Network (TTN) or set up your own gateway. This progression makes it easier to understand the difference between raw LoRa and LoRaWAN networking.
A practical example of LoRa development can be found in this blog on the XCVR LoRa Development Board, which uses the SX126x transceiver. The board supports multiple frequencies (e.g., 868 MHz in Europe, 915 MHz in the US) and integrates well with popular MCUs like Nordicās nRF52840. It also supports operating systems such as Zephyr and Mbed OS, making it versatile for developers. You can read the full article here XCVR - Engineering Technical - PCBway .
Exploring boards like XCVR helps beginners avoid complex RF design issues and gives them a ready-made platform to experiment with both LoRa point-to-point communication and LoRaWAN networking. With resources from Semtech, LoRa Alliance, Seeed Studio, and blogs, youāll have a clear path from beginner projects to building scalable IoT systems.
Hi Tim, hijacking your post since like you, I canāt create my own topic. Did you modify your final design to the point where you required a new FCC ID cert?
I am trying to discover the Seeed process for changing the FCC ID Grant.
We used the LoRa radio Wio-E5 mini Dev Board - STM32WLE5JC, SKU: 13990939 as the communications medium between an android device running our GUI and our separate product. We have been informed that we need to change the FCC ID of the LoRa radio to fall under our Grant certification. We placed the LoRa radio within an enclosure and had that assembly satisfactorily tested against the Specific Absorption Rate standard so we can safely use the LoRa device with a handheld android device.
Since this is different from the original Seeed FCC ID Grant certification we were told by our lab that we need to obtain a separate FCC ID Grant with our assembly containing the LoRa radio from Seeed.
Has anyone else gone through this process? I didnāt see anything on the website and havenāt heard anything back on my tech support requests.
