GPS not starting and BME680 not sending data on Lilygo v2.1 New
proffalken opened this issue · comments
Hello :)
I just received my LILYGO V2.1 from the official store on AliExpress and I'm trying to get it working with my Neo 6M GPS dongle.
I've uncommented the required lines, connect the GPS serial as instructed, but it doesn't show in the logs as being connected.
I've also got a BME680 connected to the board, and this is recognised on startup, but data is not sent from the board as I'd expect it to.
The data for BLE and WiFi devices is recorded and sent to TTN, so I know that part of things is working fine, but I don't see any data on ports 4 (GPS) or 7(BME680).
Have I missed a step in the setup?

*
* Scan duration sets how long scanning should be going on, before starting a new scan cycle. 0 means infinite (default).
* Scan window sets how much of the interval should be occupied by scanning. Should be >= BLESCANINTERVAL.
* Scan interval is how long scanning should be done on each channel. BLE uses 3 channels for advertising.
* -> Adjust these values with power consumption in mind if power is limited.
* -> Scan interval can be changed during runtime by remote comammand.

This appears to be because the GPS is connected on pin12, so I removed that and flashed it successfully, but I still don't see the GPS being started in the logs, and I'm still not getting BME680 data :(
- Check your GPS wiring: RX/TX swapped?
- Clear NVRAM by pio run -t erase
- Switch on GPS and BME data transmission by using rcommand 0x03 0x01 0x21 and 0x15 0x01 0x21
Thanks.
GPS wiring is correct (have checked and rechecked multiple times!) and after cleaning, clearing the NVRAM, and rebuilding logs now show:

12:48:10.448 > I (11594) src/main.cpp: Starting GPS Feed...
The GPS doesn't have a fix yet, so no data is being sent, but my understanding is that this is correct operating procedure.
The BME is also enabled, but I'm getting the following in the logs that means all the readings are zero:
12:48:10.500 > I (11645) src/bmesensor.cpp: BSEC v1.4.9.2

12:48:10.512 > E (11650) src/main.cpp: BME sensor could not be initialized
This appears to be a comms error so I'll see if I've got a 280 or similar that I can swap in and test the connections with because the wiring is definitely correct.
Is there a list of the commands for enabling things like the SDS011 sesnsor? The manual seems to cover GPS, BME, and various other things, but not the SDS011 (unless that falls under "custom sensors"?)
OK, this looks like a pin config thing.
The defaults in the code suggest that the SDS011 should be on pins 19 & 23, however these are already in use on the TTGO v2.1 as MSIO and RST for the LORA module.
I'm going through and trying different pins to find a combination that works for the SDS011, then I'll come back to the GPS and the BME680 to work out the pins for those.
The BME680 is the one that's throwing me at the moment though, because that's I2C so it shouldn't matter that the OLED is already on that bus, and indeed I can see in my logs that both devices are picked up
BME680: you're probably using wrong chip address. Try enabling this line in ttgov21new.h file:
//#define BME680_ADDR BME68X_I2C_ADDR_LOW // connect SDIO of BME680 to GND
GPS: as long as it has no fix, there will be no data sent. Go outside to get a fix. Can take up to 20 minutes after a cold start.
SDS011: not sure if ttgov21 board has enough free GPIOs if you 're already using two GPIOs for serial GPS. Check the pinout. If you find free GPIOs you can drive SDS011 on this. Paxcounter firmware will pickup data of all sensors and GPS in parallel, no limitation.
SDS data is always sent, if an SDS011 is present. SDS payload is never masked, so no need and no option to switch on/off.
If you don't need wifi/ble sniffing in you application (e.g. using sensors only), you should disable it in paxcounter.conf to save power and cpu time.
//#define BME680_ADDR BME68X_I2C_ADDR_LOW // connect SDIO of BME680 to GND
Thanks, I'll do that tomorrow. FWIW I'm using 0x76 which is what it displays as in the logs when it's detected. Do I need to actually solder SDIO to GND in order for this to work?

Thanks again, good to know, I'll check this out tomorrow as well.
If you don't need wifi/ble sniffing in you application (e.g. using sensors only), you should disable it in paxcounter.conf to save power and cpu time.
Of all the sensors I can do with out, it's probably the BME680, and then the GPS (this won't be mobile, it's just useful to have incase someone moves it).
This is for a "how many people are in the area vs. what's the air quality like" project, so the SDS011 and BLE/WiFi tracking are essential.
Just want to say thank you for both the project and your time btw - I remember seeing this idea way back in 2019 when I was running a LoRaWAN consultancy and wanted to use it back then but couldn't get the funding. It's an awesome project and I really appreciate the effort you've put into it! :)
GPS: as long as it has no fix, there will be no data sent. Go outside to get a fix. Can take up to 20 minutes after a cold start.
I'll try again tomorrow, but I had it outside for three hours with no data being sent. The "fix" LED on the NEO 6M module is flashing though, which suggests it is seeing something, but switching the TX/RX around doesn't seem to make a difference. I'll try a test sketch tomorrow as well to try and rule out the module.
BME680: I2c scanner detects your BME module at 0x76 = lower address, so probably your module does connect SDIO to GND. Thus, you must change the chip address on software side.
GPS: blinking LED on Neo 6M boards usually shows PPS pulse, this must not indicate it has a fix.
OK, I dropped the GPS and changed the code for the BME680 back to the one in the generic.h file.
I'm getting readings from the BME680 sensor now (along with a load of "error 263" in the logs that don't seem to be causing any harm!), and I can hear the SDS011 spinning up and taking readings so I'll leave it for a while and see if the zeros that it's sending back change after a few readings.
What is error 263, from where? BME680 lib/driver?
Yes, seems to be, but the readings are getting through:
The Ground had disconnected from the BME680 🤦
For referece these were the errors:

Still nothing from the SDS011, but I'm wondering if that's a dodgy connection - I'm going to try some new wires in a bit
Please carefully check your wirings and correct settings of you sensors, before opening issues here. Thank you.
OK, I'll close this for now. The SDS011 still isn't working as expected (The fan starts/stops, but no readings are sent), and when I reboot the TTGO v2.1 with the BME680 ground pin connected then it sometimes fails to read the values, but I'll get it moved over onto a PCB that I'm designing specifically for this and see if that makes a difference.
Thanks again for your patience and help.
For anyone else hitting similar issues, check the output voltage pins and GND pins on your board with a multimeter.
I found that on the board I ordered, the 5VDC pin was non-functional, and the GND closest to the 3.3v pin was also non-functional.
Once I'd moved the power supplies for the BME680 and SDS011 off the board and direct to the source, with the battery connector providing the power/GND for both, then everything sprang into life and started working.
Where did you purchase that board, from original LilyGo Shop, or elsewhere? Can you post a high resolution picture of that board here?
Sure, https://www.aliexpress.com/item/32915894264.html is the item I purchased, looks like it's from the official LilyGo store.
I've just zoomed right in and I can see that not all of the pad has solder on it where I was trying to avoid burning the OLED cable whilst attaching the pins, so it could well be that causing the issue here rather than a manufacturing fault - if anyone has advice on how to solder underneath that ribbon without damaging it I'd love to hear it! :)
This is the "original", and problems with non functional GND / 5V pins were - yet - never reported here, so a good point to check your soldering.
