I’m getting a little frustrated trying to connect to my new Torch. Bluetooth works fine in SW Maps. The problem is trying to get into RTK Config. I’ve been able to connect successfully via WiFi on my iPhone, once. It took a bazillion tries to get the Torch to go into Wifi mode. Now I wanted to …

I haven’t used WiFi Config mode in a long time on my Torch, so I just tried it. My Torch is running V2.2 My windows PC didn’t find the RTK Config SSID, even after turning WiFi On/OFF on the PC a few times. My iPhone did connect to the RTK Config XXXX successfully, and so did a few Android tablet…

I wish I could use the serial interface. I don’t own a windows machine. I can’t find any instructions for connecting via USB to either my iPhone or the Android tablet. The instructions on the Spark website assumes a windows machine. Still can’t get the Torch’s SSID to appear again.

For Android Tablet I use Serial USB Terminal . 115200 Baud Rate, connect to Port 2, send +++ [Edit: press any key] and you should see the Config Menu in the Terminal. It’s not required- but once you setup your favorite HotKeys…making config changes goes very fast. There is a similar app for Blue…

Ok, I downloaded Serial USB Terminal, and with that, discovered that the cable Sparkfun sent only charges. I couldn’t get it to connect to terminal after numerous unplugging and plugging. I swapped it for another USB-C cable and it connected right away. The serial connection is clunky, but I was …

Well, I’m not really sure what kind of data I’m getting at his point, but I see SparkFun turned on PointPerfect and after about 10 minutes over my first point I was getting 3.5” horizontal accuracy according to SW Maps. I have the Torch connected via bluetooth to my android tablet and the tablet co…

[image] ErikB: discovered that the cable Sparkfun sent only charges. Sorry for that! The cable is designed for both data and power. When I discover a power-only cable I cut it in half. You’re using v2.1 of the firmware which only support the now deprecated MQTT corrections. They work, but as…

Point of Clarification: @sparky , I’m fairly confident that all the Sparkfun RTK products will function properly when sending NTRIP corrections over Bluetooth from various smartphone/tablet apps…no matter what FW version. I assume you were specifically speaking about the built-in NTRIP Client insi…

Ah! That’s a really good point. All our RTK firmwares and products work with the built-in NTRIP client, or receiving corrections over Bluetooth (for example using SW Map’s NTRIP Client). So v2.1 can be used with PointPerfect NTRIP/RTCM service, we would just need to get @ErikB some new credentials. …

I would like to update the firmware to 2.2. I’ll see how that goes tonight. I only have Mac computers, an iPhone and an android tablet. I went out this morning to start on my project at a local park. I was not able to get any RTK fixes. Only DGPS. Accuracy was between 1.2 and 1.5 feet for 15 points…
