Not sure to understand your question… (sorry English is not my mother language)
how did you get that device EU ?
Within TTN, we assign device address prefixes to “regions” (for example, device addresses in the eu region start with 26 01).
this is a node join
I don’t understand why your question…
but Device address I have come from TTN console.
TTN node= 26011CB9
But event data I read on my gateway for LSN50 is without devaddress
It’s like my LSN50 want to make OTAA activation but I ask for ABP activation.
My guess from a simple bit of deduction is perhaps from Objenious/Digimondo. From the Address Space link you shared @BoRRoZ:
0x28/0x29` Germany, Switzerland, China: DIGIMONDO GmbH (0x14)
and this press release:
@kelu28 The reason BoRRoZ made that comment is clear from the link he shared. The information you shared from your console doesn’t match a device that’s Dev EUI was created by TTN. It also doesn’t at least from my reading make it the issue of your problem. But when you set up/added the Device to your console did you input the Dev EUI for your node or did you allow TTN to create it for you? The documentation states it should be something other than x28 which is why BoRRoZ made the comment he did. Just my 2-cents and thoughts though.
I am born the 28 November 1982, And i put the dev_eui by my self ! Must I change this value?
So, read the link.
“If you plan to switch to ABP anyway, click the button have one generated for you”
I make it, but the TTN website give me the same Dev EUI.
And naturaly no change.
Have you another idea?
What must I do?
I have contact the dragino support.
They ask me to update my LG01.
Make it but not the solution.
I think the error come from the DEv EUI.
But how to solve it?
my actual parameter for ABP:
DevEui= 00 04 A3 0B 00 1F D3 95 DevAdd= 26011A96 NwkSKey= 95 78 A6 B0 AD 5E 50 BC 1C 40 83 5B 23 56 2B 9C AppSKey= 3A 66 2E 1B DE 3C 25 E3 29 30 FD E4 2D B6 0B 5A
please help me !
Thanks to help me.
First I make a AT+FDR
then disconnect the jumper and reconnect it.
SW1 is in flash mode
My AT command:
AT+TDC=30000 AT+NJM=0 AT+TDC=10000 AT+APPSKEY=3A 66 2E 1B DE 3C 25 E3 29 30 FD E4 2D B6 0B 35 AT+NWKSKEY=95 78 A6 B0 AD 5E 50 BC 1C 40 83 5B 23 56 2B 9C AT+DEUI=00 04 A3 0B 00 1F D3 95 AT+DADDR=26 01 1A 96 AT+APPEUI=70 B3 D5 7E D0 01 2E C3 AT+JOIN
Each time, the LSN50 say “OK” and finally “Joined”. But on my LG01 gateway I see a join request from the LSN50. Why? I am in ABP mode?
Next I do a reset and the LSN begin to speak in ABP on the only one channel of the LG01, but the gateway never hear anything.
In parallele, if I send AT commands to the LSN50 in order to use OTAA mode and connect to the Objenious Lora network, that work!..
Finally I don’t understand what I make false. Help !
I have a Dragino LG01 gateway too, and oh boy… They did some shit when designing this gateway.
It’s improbable to get a LoRaWAN downlink from this gateway.
You can check the open source code if you understand what’s going on there.
The code doesn’t care about any timestamp, that’s mean the gateway doesn’t know the right time to send the downlink to the node.
Usually the node open RX1 and RX2 on a specific time after sending the message, and if the gateway doesn’t have a good time synchronization the device never receive any downlink.
Summarizing… The Dragino LG01 downlink doesn’t work, that’s mean only ABP uplink…
I probably gonna make a code trying to fix this.
That would be awesome, I am struggling since August to get the downlink working and could not understand why.
Hope you can help me.
I cannot connect to TTN, tried a lot, several times but the gateway does not connect to TTN. I do not see the global LED working.
Never seen ;-(
Would be really appreciated if you can help me.
Thanks in advance.
