SeeedStudio Loko GPS Tracker - GPS tracker with LoRa P2P and LoRaWAN problems

[KingRat0011]

I ordered a unit form SeeedStudio, I ordered it on the 15 Sept and it only arrived on 17 Nov, as they did not have any stock... but I'm having problems with it, I program the Air Unit like this,

The Ground Unit like this,

But I get some weird devices ID 11 and 77 in the app, Device ID 77 is in China somewhere and 11 is in the correct GPS position in South Africa, and no battery voltage is being displayed

In the documentation it states, that,

ID1, Is the pairing code between the Loko Air unit and Ground unit. It should be the same in both of them. Must be 2 digits. Where do you set this on the ground unit? As in the ground unit config, it says, So there is only a place to set the ID2, which is the ID of the Loko Ground unit

Reading device information...
-> Read command sent
-> Loko v1.71

-> .is_p2p_encrypted = 0
-> .is_debug_output = 0
-> .gnss_mode = 1
-> .is_extended_packet = 1
-> OK

Am I missing something?

Hi @KingRat0011

It shows a location in China because the unit was previously tested there. Loko stores its last known GPS data in the internal log. If it cannot obtain new GPS data within 60 seconds, it will transmit the most recent log entry and then go to sleep.
Have you tried testing it in an open area? Especially for the very first GPS fix, please power it on outdoors. Since the last recorded GPS point is on the other side of the world, the initial lock may take longer than usual.

Regarding the “no battery” issue — I see your Loko Air units are running firmware version 1.71. Please update them to the latest firmware, as we have changed the battery data format in the application.

Hi @tomipiriyev
I did the update following the procedure on the Air unit, I'm getting updates now it seems, but the battery V is still blank

I updated to this file, is that correct? loko_v1.78.hex

Thanks for the help, at least I'm getting something now
