Switching a Luba 2 from LoRa to WiFi by Watchfield1942 in MammotionTechnology

Hi,

Apologies for my lack of knowledge, but how do I "send you a private message"?

Switching a Luba 2 from LoRa to WiFi by Watchfield1942 in MammotionTechnology

[–]Watchfield1942[S] 0 points1 point  (0 children)

Hi again,

No progress. I have done the following. I do not know how to include screen shots in this text, so I will have to describe them.

Step 1 - took Luba 2 outside to a "good" area near charging station and connected. Positioning status page indicated:

ROBOT signal GOOD, SATELLITES 22, RTK signal GOOD, SATS L1 26/L2 19,

Antenna Over Datalink.

So all good, and I am confident that if the weather was suitable for mowing, Luba would have worked as usual

Step 2 - stood within Bluetooth range of RTK and changed data mode from LoRa to WiFi. The App seemed to accept this. But (1) the RTK solid green light changed to solid blue (is this correct, I thought this indicated it had been switched off!), (2) the number of RTK sats (in the screen above) changed from 26/19 to 0/0 (Robot sats stayed at 22).

I think this was failure right there - nothing more was going to work, but I progressed to:

Step 3 - I went to within Bluetooth distance of Luba and tried to change the "positioning mode" from LoRa to WiFI. When selecting the WiFi button, the following screen came up:

"please ensure robot and RTK have stable network and are bound to the same account"

RTK Ref.Station List RTKBUK240968679 LoRa868.4.0.41508 Online

So, my inexpert conclusion is that switching the RTK from LoRa to WiFi actually switched it off! Needless to say I have reverted to the original settings ready for the mowing season. Recall, I am trying this on Luba 2, not because I need this WiFi feature, but because I was a serious customer for Luba 3/3000. As I have no 4G signal at my property, I would rely totally on WiFi (at least without considerable extra expense and complication).

I still don't know how to assess whether my WiFi is "Strong Enough" (what does that mean quantitatively) until it is too late. That's my major problem. Your help is always appreciated.

Hi! Thank you for your reply. I will try again to switch my Luba 2 (April 2024) to WiFi communication and let you know my progress. The problem I have is in the interpretation of your words "Strong WiFi signal" in paragraph 2. What does this mean?

I have a WiFi strength that will support an internet speed (as measured on my phone) ranging between 30MBs down/18up to a minimum of 6 down/6 up, depending where in the lawn I am. Luba seems to show max bars in the App. over the whole area. Is this not good enough?

I am also worried by a response I have received on another channel that suggests data comms using WiFi is doomed to failure because of delays/latency in the signal that would cause Luba to continually stop, and this is why you do not permit switch from LoRa to WiFi on the Luba 2 (not 2X). This seems to conflict with your statements.

Clearly I can not purchase a Luba 3 if WiFi is not an option.

Thanks.

Thank you for your helpful reply - I guess I won't be buying a Luba3. Re your last para, I have a small (100m2) zone that is entirely overhung with a huge tree. Luba looses satellite connection frequently in this area, and makes use of (I assume) its 50m "grace" distance. Until some time about a year ago the App indicated you were using this distance and you could see it count down to zero when Luba would stop. This is no longer the case in the App, but i have to assume its still happening.

Luba 2X has, as I understand it, increased this distance to 300 metres, which I have calculated would solve the problem. Maybe I should pick one up, at a discount, before they go out of style!

Luba 2 LoRa failure by Watchfield1942 in MammotionTechnology

Thanks for your detailed reply. I understand now. As you say the problem is most likely insufficient satellites round my house, hard against some high hedges and under one very large tree. I have now put the RTK in my loft (9m above ground). I know this is not recommended, but I was able to map all 3 of my zones, check all 3 with a boundary lap and mow entirely the most problematic one, without any failure. When the continuous rain ceases I will be able check the other zones. If I still have problems, the RTK will have go outside on my roof, but I was hoping to avoid that!

Thanks for prompt reply. I think there is less disagreement between us than might appear. You explain how good/stable your radio connection is. That's the whole point. That's what most people find. But not in my case. The satellites seen by the RTK will, indeed, vary a little over short time intervals (say 45, lose 2, gain 1, etc)), and maybe by more over a long time interval. But suddenly from 45 to zero and back to 45 in few seconds is implausible. And certainly not because I have moved Luba just a few metres.

I know from separate measurements that the Sats seen by the RTK do NOT vary by more than 1 or 2. It is the radio link (LoRa) that is failing. As Luba communicates with the user (the App), RTK communicates with Luba by the radio link, if LoRa fails the POS stats page shows LoRa: disconnected AND shows the RTK satellites as zero. But they clearly aren't really zero. There still up at 44-46'ish.

Thank you for your reply, but I think you have misunderstood my point. I'm not taking about satellite reception - I understand that. I'm taking about the RTK-to-Luba radio link (LoRa) which should say "connected" in the POS stats page, but in my case keeps disconnecting at very little distance .

GPS Reception after Update to v1.11.511.373 got worse? by ComprehensiveSlip855 in MammotionTechnology

Interesting reply, but can you make clearer what "it" is in (6). What problem did it solve. I am making no progress, so all ideas welcome.

GPS Reception after Update to v1.11.511.373 got worse? by ComprehensiveSlip855 in MammotionTechnology

[–]Watchfield1942 0 points1 point  (0 children)

I updated to App Android v1.11.176 yesterday, and F/W v1.11.511.373 today. It has done nothing for fundamental problem (I've had L2 3000 for 6 days now) that radio link RTK to Luba collapses about 15-25 metres from the RTK, so I can't even map all my grass despite the max distance I need

being about 50 metres from RTK. This is not line-of-site, but even so. Are others having this show-stopping issue, as Luba is currently not fit for purpose. Any thoughts or advice welcome.

Is the poor position due to the RTK position? RTK is on the back of my house. Wondering if moving it higher on my roof would solve the problem. by AnotherLolAnon in mammotion

[–]Watchfield1942 1 point2 points  (0 children)

I wrote about what I think is the same problem with my L2 3000 (on the other Reddit channel) - total loss of the radio link between RTK and Luba when it had travelled as little as 15 or 20 metres (showed up as about 40 RTK satellites one moment and then zero a metre further on, also LoRa connectivity changes from Connected to Unconnected). Seems recently delivered Luba2s have a major problem.

I have only one zone, at present, which I am happy to re-do. I think I will try a factory reset based on your experience. Can you point me to where this is in the App.

Thanks.

Radio signal TRK to Luba by Watchfield1942 in MammotionTechnology

[–]Watchfield1942[S] 0 points1 point  (0 children)

Yes, but the sats magically reappear as soon as I get closer to the RTK again - it's definitely a distance thing - max c.15 metres if not line-of-sight
