Hi All, Can someone help me ? I’m trying to communicate between a feather 32u4 LoRa (rfm95 module) and rn2483. When communicating between two feather (RFM95) with raw LoRa => OK. When communicating between two RN2483 with raw LoRa => OK But when communicating between a feather and rn2483 => Fai…

I just found the solutions: RFM95 and RN2483 were configured with different Synchronisation Word. Default for the RFM95 is 0x12 and for the RN2483 0x39. If your using the RadioHead library, in the initialisation code, just add: spiWrite(RH_RF95_REG_39_SYNC_WORD, 0x39);

Hi, just want to ask - where did you find information about Default Lora Word for RFM95? in RadioHead library I found only one mention about Lora Words only in RH_RF95.cpp : // Set up default configuration // No Sync Words in LORA mode. setModemConfig(Bw125Cr45Sf128); // Radio default

[image] d00m: just want to ask - where did you find information about Default Lora Word for RFM95? The RFM95 ‘datasheet’ is not complete, you will find the default sync word defined in the SX1276 datasheet. If the Radiohead library does not set the sync word, then the default will be used.

thanks, if I understand all correct - LoRa Sync Word from SX1276 datasheet is 0x12? sx1276.pdf 2.05 MB page 91 and page 115 So in RadioHead lib should has the same value?

[image] d00m: So in RadioHead lib should has the same value? I have not been through the RadioHead library myself to check if it sets or changes the Sync word or not, so as I said above; “If the Radiohead library does not set the sync word, then the default will be used”

Hi, Perhaps this is a new topic, but it is very similar… I am using the RN2483 (microchip) and the RFM96. Both are controlling by Arduino using the UART and SPI. I set up a raw communication using Lora (not Lorawan). The RN2483 is TX and RFM96 is RX. Parameters, like: Freq, SF, CR, Sync word, bi…

Hi, I am also trying sometime same like you did, but with no success, can you please guide me, i am trying feather rfm95 and rn2483 with LoRa tx, i guess the problem is same as you have pointed out with sync word, but i am not able to set sync word for rfm95, maybe radio head library that i am usin…

You asked the same question over in the Arduino forums, The advice here is the same, prove that you have the Arduino RadioHead library RX program working first with a matching RadioHead TX, before trying to read packets from the RN2483. Please appreciate that this is a support forum for The Things…

Hi, i am trying to achieve the same, communicate the RFM95 with the rn2483 but i can’t make it work. In both devices y configured the same parameters, spreading factor, bandwith, coding rate, frequency, sync word but i can’t make them communicate with each other. Do you have any idea of what would b…
