Stuck with ns.up.join.cluster.fail

[mbechc]

I have 3 Tabs (Browan Temp + Humidity)

All 3 devices shows with “Last Activity” → Newer

All 3 devices has a Live Data - activity log, that is full off
ns.up.join.cluster.fail messages.

On the Mikrotik gateway
I see only Join-Request in the Lora Traffic log
under the udp packet forwarder I see;

• Valid RX Count: 1071
• RX Forwarded: 1071
• ACK Percentage: 99
• Downlinks: 0
• TX Count: 0

I conclude Join Request flows through gateway, ends under my devices in the Application on TTN - but devices are newer fully registered and therefore I newer start receiving data

[Jeff-UK]

Registered using Device Repository or manually?

Can you confirm all keys correct?

[Johan_Scheepers]

What is the distance between your gateway and nodes?

[Jeff-UK]

@mbechc

On the Mikrotik gateway

Can you show what you see on the TTN Console?

[mbechc]

Gateway is between 10m and 50m between the 3 sensors and the gateway. 2 Sensors are indoor together with Gateway, one is outside (50 m)

Gateway is equip with 6DB Omni antenna - MikroTik Routers and Wireless - Products: 868 Omni antenna
The Mikrotik has been set to 6DB antenna gain.

@Jeff-UK I took a few screenshots on how I registered the nodes, I used Device Repository

[Johan_Scheepers]

I would defiantly make sure there is a brick wall and 10m between the gateway and node, to me it looks like your RSSI is to high.

[Johan_Scheepers]

Your sensor registration looks fine at the moment. First get the RSSI down and them to join.

[mbechc]

I will move one of the sensors aprox 1000m away

Included is screenshots from Lora traffic as seen from Mikrotik GW

[Johan_Scheepers]

@mbechc

I will move one of the sensors aprox 1000m away

You could just that 4 bricks and stack them on top of each other and put the node behind it, brick wall done.

You want -65 to -110 for the RSSI.

Bit of a pain to drive 1000m to the node each time.

[mbechc]

Perhaps I should remove the external antenna and use the built-in 2 dBi antenna, I’m really just trying to have indoor sensors anyways.

[Jeff-UK]

Yes to that - prove GW/node combination works correctly 1st then look at ant improvements - 6dbi at the upper end of what I would ever consider - 'cause…well forum search helps! If you are only working with local nodes closer to isotropic pattern works best for allround coverage…

Lots of GW join requests but no join-accepts seen at the GW or in console? Suggests registration problem - have you applied the correct AppKeys as provided by Browan?

What RSSI/SNR levels are you actually seeing? GW & Devices set to same freq plan? RX2 on?? RX 1/2 delay set at ??

[mbechc]

Internal antenna is now in use and lowered RSSI to -70

Still I only see loads of Join-Request

[Johan_Scheepers]

Please double check your keys.

[mbechc]

I took a picture of the back of one of the sensors, I will upload pictures from the registration proces. Hopes this will help - catch my errors

I wrote Join / Dev EUI as written on the back of devices, I pressed Generate on the AppKey

I will create a second device but swapping Join / Dev EUI even though I pretty sure that I read Browan manual correct

[Jeff-UK]

1st is App Eui (Join EUI) 2nd is Dev EUI…what is also critical is the AppKey - keep that obscured but double double check you have that right - it will be unique to each device, make sure you havent swapped between devices

[Johan_Scheepers]

@mbechc

I pressed Generate on the AppKey

The key needs to match what is coded into the device.

[Jeff-UK]

@mbechc

I pressed Generate on the AppKey

Ah that wont help as you then need to programme that into the device! They come with a key pre-assigned - usually on a slip of paper! If you find it simply go in and edit and save changes…hopefully LNS will then recognise your device…
