GPS/GNS for SIM7000 #8

Closed toddsandercock closed 5 years ago

toddsandercock commented 6 years ago

Hi,

SIM7000 units use GNS AT commands as per the manual. I know AT+CGPSPWR? mysteriously works on the 7000 at the moment but it might be worth changing enableGPS to this:

`boolean Adafruit_FONA::enableGPS(boolean onoff) { uint16_t state;

// first check if its already on or off

if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) { if (! sendParseReply(F("AT+CGNSPWR?"), F("+CGNSPWR: "), &state) ) return false; } else { if (! sendParseReply(F("AT+CGPSPWR?"), F("+CGPSPWR: "), &state)) return false; }

if (onoff && !state) { if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) { if (! sendCheckReply(F("AT+CGNSPWR=1"), ok_reply)) // try GNS command return false; } else { if (! sendCheckReply(F("AT+CGPSPWR=1"), ok_reply)) return false; } } else if (!onoff && state) { if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) { if (! sendCheckReply(F("AT+CGNSPWR=0"), ok_reply)) // try GNS command return false; } else { if (! sendCheckReply(F("AT+CGPSPWR=0"), ok_reply)) return false; } } return true; }`

Thanks for the comment! Yea, I noticed that too. Actually "AT+CREG" mysteriously works as well but "technically" it's supposed to be "AT+CGREG" instead. I think this was SIMCom's attempt to make it easy to migrate from the other 2G and 3G modules but I'm not sure. I'll go ahead and change it for good measure though. Thanks!

toddsandercock commented 6 years ago

Oh Nice. It looks like CREG and CGREG are both in the commands list but the CGREG is better because of the CAT M1 and NB IOT stuff

AT+CGPSOUT I don't think works on the sim7000 for NMEA enable. AT+CGNSTST is the one. Although this probably wouldn't get used that much.

boolean Adafruit_FONA::enableGPSNMEA(uint8_t i) { if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) { if (i) return sendCheckReply(F("AT+CGNSTST=1"), ok_reply); else return sendCheckReply(F("AT+CGNSTST=0"), ok_reply); } else { char sendbuff[15] = "AT+CGPSOUT=000"; sendbuff[11] = (i / 100) + '0'; i %= 100; sendbuff[12] = (i / 10) + '0'; i %= 10; sendbuff[13] = i + '0'; return sendCheckReply(sendbuff, ok_reply, 2000); } }

Sorry, that line of code is literally one line :)

toddsandercock commented 6 years ago

Yeah just edited it

botletics commented 6 years ago

But I see what you mean, I changed that as well, testing now!

botletics commented 6 years ago

And yup, "AT+CGNSPWR" works, so we're good there. Testing the NMEA command.

botletics commented 6 years ago

The "AT+CGNSTST" errors out if I try to set it either way but maybe that was fixed in a later firmware version. I'm currently testing on 1351B01. When I get my next production batch of boards I'll grab one off the line and test it :)

I uploaded the new .ccp file.

Thanks again!

toddsandercock commented 6 years ago

Hmmmm interesting. I too get the same error

+CGNSCFG=1 works but it only puts the NMEA to the NMEA port via USB.

Maybe this is worth keeping open until I test it :)

botletics commented 6 years ago

Sorry, I can't tell, but are you testing this with my shield or some other SIM7000 device? It's perfectly fine if you're not but just curious so I know if we're on the same page.

toddsandercock commented 6 years ago

At the moment I just have a SIM7000E just plugged in via USB. Have been reading your code to understand how the board works. Makes it much easier to understand the manual.

Want to connect the module to an ESP32 when it finally rocks up. I think Chinese new year might push out a few things.

Will your new board have the SIM7000G?

Once the SIM7000G comes out and I get my hands on it yes, I'll have that version available for sale as well.

toddsandercock commented 6 years ago

Sweet I will buy a couple of them when you get them. Any code I come up with to optimise the library for CAT-M1 and NB-IOT I will send you. The module is really cool and has some great features.

Thanks! Check out my Indiegogo campaign or Twitter for the latest updates. I'll definitely post about the SIM7000G when I get a hold of it.

botletics commented 5 years ago

I can confirm that AT+CGNSTST now works with firmware version 1351B02SIM7000G. Use AT+CGNSTST=1 to enable NMEA output to AT port, and AT+CGNSTST=0 to disable.
