Reyax RYS8830 GPS/GNSS Receiver Module EVB not working
Posted: Wed Oct 11, 2023 3:06 am
Hi,
I have been working on a little project and I am stucked on this since some weeks ago, i am very newbie on it, could you help me out? I want to get the gps data using RYS8830 EVB but I am getting "No GPS detected: check wiring." always, both devices connected to usb laptop. Using the software I could see the location very accurate.
Devices list:
1) ESP32 DEV KIT v1
2) Reyax RYS8830 GPS/GNSS Receiver Module EVB
3) 8-channel Bi-directional Logic Level Converter - TXB0108 (3.3v - 1.8v)
My wired is the following (jumper activaded on UART protocol on GPS EVB): Based on the documentarion I have used the RX,TX,Ground and 1.8V output as following:
EVB RX -> ESP32 TX
EVB TX -> ESP32 RX
The code is:
Usingthe vendor software:
Thank you in advanced!!
