I would appreciate any help. Thanks.

You can try to use chirpstack on our cloud to do the same test and see if there will be the same problem. You can send me your frequency band configuration and I will apply for an account for you to test. :grinning: :grinning: :grinning:

Hello @Nicholas Actually the gateway that I have cannot use chirpstack because It is not mine, It can only connect LoRa server orbiWAN. But It´s a good idea to prove with other server, but I don´t have access to other gateway. My configuration its:


Thank you so much for your help :smiley:

I can’t connect LoRa server orbiWAN to do the test, but when I use chirpstack to use downlink, it is normal at present, and there is no error you have made, which leads me to be unable to confirm the problem.

Hello @Nicholas thanks for the answer, I want to ask you what parametres can you configure in Chirpstack for downlink connection?, maybe in this are the problem. In orbiWAN I can only configure rhe rx slot 2 window in data rate and the option are SF7 - SF12 and the Downlink slot delay. Thanks for the help.

Commercial gateway: can send rate, transmit power, delay and other parameters
Raspberry PI gateway: configuration file and written parameters, just need to configure the issued port and content
I hope this helps you :grin: :smile: :smile: :smile:
