I connected a passive GPS on a LoPy device on the GPS pin. What is the pin number to read those values?

@rskoniec
Thank you :)P.S. price?
About 30$

BTW, I'm using this one SparqEE GPS
Can you bring some light about it (if you have one) - datasheet is realy poor without anyd details.
How fast it is (hot start, cold ...) and how accurate?
Power consumption?- Hot start - aprox. 1-2s
- Cold start - aprox. 30-40s
- Accuracy - aprox. 3-5m (good view open sky)

@rskoniec What antenna do you recommend to use? It have to be as small and light as possible. That was the reason why i chose the passive ufl antenna. Or should i wait until the Pytrack expansion board of Pycom is released?
If we are talking about GPS antenna many GPS-RX modules are in 2 flavours:
- with integrated (built-in antenna) sometimes with uFL connector - for example this BTW, I'm using this one SparqEE GPS
- with uFL connected external antenna - for example this
PyTrack can be pre-ordered here with shipping in this month, so I guess it's up to you how fast you need GPS functionality and amount of money you'll want to spend on it.

This could be good start for GPS adventure: ;o)
@johnmcdnz said in LoPy UART for GPS not reading data:
@livius It's this
http://www.addicore.com/NEO-6M-GPS-p/231.htm
available and cheap :-)
(I don't buy from that website, just a local supplier of the same thing)@affoltep said in LoPy UART for GPS not reading data:
@livius This module here, as well cheap and with integrated antenna.

@Shaun tnx for help

@lawrence
You have connected a passive GPS antenna to the uFL connector meant for a WiFi antenna .
There is no GPS receiver in the LoPy or WiPy.
You will be required to connect an entire GPS module to the LoPy

I'm not using an expension board i connected the GPS antenna on the LoPy itself. There are 2 possible antenna possibilities ( LoRa and gps antenna). i'll post a picture after this post.
AFAIK 2 uFL antenna connectors are for WLAN/BT and LoRa. According to your picture you've connected your GPS antenna to uFL WLAN/BT connector.
Anyway, your setup would be OK if LoPy board would have GPS receiver built-in. AFAIK it hasn't.

@rskoniec
i need it in p notation this is wat i tried.from machine import Pin
from machine import UART#Interface definitons for GPS
gps_pps = Pin('P23', mode = Pin.IN)
gps_enable = Pin('P8', mode=Pin.OUT)
gps_enable(False)
gps_uart = UART(1, 9600)
gps_uart.init(9600, bits=8, parity=None, stop=1)gps_enable(True)
while True:
if gps_uart.any():
print(gps_uart.readline())

If you need pin number in P or G notation you have to give us more details:
- Are you using Expansion Board or breadboard for GPS connection?
- Can you share a photo of your setup?
