Greetings!
I’ve been dealing with some issues here while changing devices from a network server to another.
I have some devices created in the internal network server of a gateway. This was done using the MQTT integration, uploading all the information through MQTT messages using the 8080 port. We had no issues so far. 90% of the devices were joining and sending data. We also used an internal decoder to send a data to another server.
Recently, we had to move all these devices to an external network server independent from the gateway, so that for devices that couldn’t join they might find another gateway to send data through. I did the “migration” by basically extracting the information for the devices (devEUI, AppKey, activation tokens, fCnt, devAddr) straight from the SQL of the gateway and importing it into the SQL of the new network server. After that I used the API deactivation command using MQTT to deactivate the devices in the NS of the gateway and activating them for the new external NS using the previously mentioned information. With this I was checking that devices were sending their messages through the external network server using the same gateway. Meanwhile the internal NS wasn’t showing these messages, as expected.
My issue is that apparently since then the data that has been coming in is wrong. The base64 message when translated to HEX is throwing values that are either too big or negative for a device that measures water volume. I don’t know what is causing it. As far as I understand there has been no changes to the decoder or the devices. I don’t know if maybe it was an issue during the migration process and one of the values like fCntUp/nFCntDown.
I have to mention that I did this same process with a couple of other devices for another gateway and we are not having this issue at all. The devices are the same type and are programmed the same and they are sending their messages properly. The devices with this problem were all sending the correct values until the migration was done and I am trying to do a rollback re-activating the devices on the internal NS while deactivating them from the new NS to see if the issue is somewhere else but at least keep the data.
Any ideas would be appreciated.
Thanks.
