Has anyone tried 2.4GHz LoRa?

ralphjy
ralphjy over 3 years ago

I had not heard of 2.4GHz LoRa until I came across the Semtech SX1280.  I was looking for a device or module that could do both LoRa and BLE.

It combines BLE and LoRa in the same transceiver by moving the LoRa frequency to 2.4GHz so that the antenna can be shared. Apparently it's been around for a couple of years. I was wondering if anyone on E14 has tried it and what their experience has been.

I have a RAK4631 that combines BLE with LoRa at the conventional frequencies (I use the US915 band).  It uses an nRF52840 for BLE and an SX1262 for LoRa - and uses separate antennas...  I was writing a blog post about it but it got sucked into the black hole of  moderation.

    The SX1280/SX1281 are in distribution and the chip prices are reasonable - about $6. The lower priced dev kit is $75. There are castellated modules from EBYTE that are selling on Amazon and AliExpress…

    I came across the HOPERF RFM99W module some time back but never got round to ordering them to try out... and yes you can use BLE and LoRa with single antenna... but note its only compatible at the BLE PHY layer. You'll have to do the rest or find a vendor that builds a compatible BLE stack for you.

    I know you can order samples from them directly at a good price as I cannot see these modules on sale anywhere else...

    I think that's probably why so few people have tried and made noise about... but then again... there's probably others in the e14 community who have. I'm curious too.

    Hi,

    look for this similar LoRa modul:

    RFM98P 169/433/470MHz Enhanced Power RF LoRa Transceiver Module NEW!_LoRa long range transceiver module-Hoperf

    It operate at 169/433/470MHz (RFM98PW)  and 868/915MHz(RFM95PW) ISM band.

    The used controller on the demo kit is a PIC1615.

     https://www.hoperf.com/data/upload/back/20190305/RFMXXB_TOOLS.pdf

    A similar demo kit comes with a display 

    https://www.hoperf.com/data/upload/back/20181122/HopeRF_RFDK_RFMxx_DEMO_V2.1_operation_manual.pdf

    Best Regards

    Hi Gerald,

    The modules that you referenced are the standard sub GHz LoRa not the 2.4GHz.  I am interested in looking at the LoRa/BLE hybrid capability using a single antenna.  I want to get a sense of the operational tradeoffs vs a unit that I have that uses 915MHz LoRa and BLE with separate antennas.

    The RFM99W is at a similar price. Ah yes, forgot about the EBYTE SX1280 modules. Yes as you say, they're available on aliexpress etc. I've been dying to try them out. Thought they would work well for hacking a radio controlled car to give extra distance etc.
