"Hi!
Check out my RTKLIB settings:
NTRIP: RTCM 3
Elevation Mask: 20 (if sufficient number of satellites)
SNR Mask: 40 (to prevent cycle slip)"

Kuo Hsu replied to Andrew Witte's discussion NavSpark Arduino IDE download??
"Yes, you do need to get a UART adapter to get Serial.print() data on your PC. You must purchase a UART adapter that is 3.3V since NavSpark is 3.3V type.
TX to RXD2 (GPIO 1)
RX to TXD2 (GPIO 2)
GND to GND
VCC33 (out) to VCC
You don't need to unplug t…"

Kuo Hsu replied to Andrew Witte's discussion NavSpark Arduino IDE download??
"You're welcome. All programs require GnssConf.init(); in void setup().
If you uploaded the "demo_hello_world.ino", the hello world messages will output from TXD2 (GPIO 2) at 9600.
The GPS Status LED (GPIO 0) will only light on if you program it."

"1. Connect NavSpark to the Computer via USB.

2. Connect BOOT_SEL with RF_GND with a jumper and press reset.

3. Open GNSS Viewer. Select the correct COM port and baurate (default is 115200). Press connect and check if the boot status is "ROM (OK)".…"

"If you previously loaded your NavSpark-GL with "Leon3 without GNSS Library", you need to upload the sketch using default ROM. Connect BOOT_SEL with RF_GND and press reset. Connect NavSpark with GNSS Viewer (select the correct COM port and baudrate (…"

"You can upload your sketch by using the GNSS Viewer (http://navspark.mybigcommerce.com/content/GNSS_Viewer.zip). After verifying the sketch on Arduino IDE, the file should be located in C:\Users\YourUserName\AppData\Local\Temp. Select the correct CO…"

"From my knowledge, GnssInfo.isUpdated() will only return true when NavSpark has a fixed position."

Kuo Hsu replied to Brian Kelley's discussion Garbled Serial Output
"Strange, I ran the same code with GnssConf.init(), and my serial output is clean.  Which serial monitor are you using?  If it's still not working, upload your sketch using ROM mode (shorting BOOT_SEL with RF_GND and press reset once). After you fini…"

Kuo Hsu replied to Brian Kelley's discussion Garbled Serial Output
"Add GnssConf.init(); in setup.
e.g.
void setup()  {
GnssConf.init();
Serial.begin(9600);
}"

Kuo Hsu replied to Jeroen's discussion Problem running adaptor board example code
"I tested the SD_Card_Access_Example, and I didn't run into any problems.  You can try reformatting your SD card before inserting it into the NavSpark Adaptor Board.  I hope that solves the problem."

Kuo Hsu replied to Edwin Wisse's discussion Tutorial: using a nokia lcd screen
"This demo wasn't suppose to be released until the new website is up.  Fortunately, GnssInfo.time.decisecond() does exist.  It was added on February 17.  https://github.com/NavSpark/Arduino-1.5.6-r2-Src-NavSpark/commit/d9...
That's odd, I personally…"

"I believe you have visited our new website that hasn't been officially released yet.  If you download our newest executable Windows Version (.zip, ver 1.5.6 r2, 20150331), you should be able to compile and upload the Nokia 5110 code just fine."

Kuo Hsu replied to Skat23's discussion RTKLIB - How can I improve solutions?
"The pictures are still too small for me.
You have the ideal HDOP values.  For 6 satellites, your rover and base may not be too far apart in distances.  In most cases, you need at least 8 satellites to be able to achieve a fixed solution.
You may als…"
