support SX1278?

[xiaohuasheng]

I connect Raspberry 3 with the SX1278 radio module.
My SX1278 radio module supports 433MHz, so I edit the global_conf.json:

Run the gateway, it displays:

but when I send data from a lora end-device, it can't receive anything, it supports SX1278 or not?
moreover, as the sheet shows, mode 10's BW is 500, but if I set BW in global_conf.json, such as 433, which will work?

thanks a lot!

BW is not the frequency. So it is not the parameter that you have to change. Use the freq field to indicate a frequency. Please, have close look at the README: https://github.com/CongducPham/LowCostLoRaGw#running-in-433mhz-band regards, Le 14/01/2017 à 09:53, xiaohuasheng a écrit :

@CongducPham Thans for your reply, I have read 433MHz part of README, and did that as it suggests, the result is:


I run the same command but have two results, why? and I still can't receive data from end-device, how to debug it?
also, I don't know the meaning of the tips like"Power: state 0", what "state 0" represents?
Hope for your answer!

[CongducPham]

state = 0 means everything is OK. Here, setting the frequency seems to give an error of -1 which should not happen in the latest version of the SX1272 lib. I suspect that you are using an old version. Get the latest version of both SX1272.cpp and SX1272.h on the github and retry.

Anyway, normally, even if the returned state is -1, the gw should be running on 433.3MHz. If you don't receive anything, check if your end-device is on that frequency. What example are you using? Make sure that you also have BAND433 uncommented in the example.

I'm tested, support perfect. please change mode to 1. i have two sx1278 model. one as gateway, one as node. can send and received.
