How do I configure QGNSS 2.0 to talk over TCP/IP instead of a Serial Connection?
Help is appreciated.
Can you provide more detailed instructions or logs?
Thank you for helping. I don’t have any logs.
I currently have my LC29HDA connected to an ESP32 WROOOM via serial connection. The software in the ESP32 allows me to set-up a Socket Server which in turn should allow me to reach the LC29HDA via TCP/IP. My question is, can I configure QGNSS to talk to the LC29HDA over port 23 TCP/UDP? Maybe through the file option? I don’t know, please let me know.
I agree if it’s not available now. Question, I noticed you linked the Satrack for Allystar modules. Are you using these modules at the moment? How is it working out for you?
I use their software also for quectel lc29h module…for view nmea or rtcm data.
For send commands over tcp use sscom.

Thanks for the tip! I think it’s Genius and a great work around. Are you also using a ESP32, if you don’t mind me asking?
I prefer to use esp8266 flashed with GitHub - jeelabs/esp-link: esp8266 wifi-serial bridge, outbound TCP, and arduino/AVR/LPC/NXP programmer
and strsvr of rtklib for send corrections ; lefebure or swmaps for monitor.

Would you mind sending me the file to SSCOM. I googled it but most of the links take me to shady sites. I’m afraid to download a virus.
One other thing, I can’t seem to get my ESP32 to transmit any data through Wifi. My connection to it via TCP/IP using Satrack is solid but Satrack isn’t receiving the data as far as I can tell. Have you run into this issue? If so, any solutions? I know my LC29H module is working correctly, I tested it with a USB to TTL Serial connection.
I noticed your version of Satrack is different than mine. Can you please send the version number you’re using? I’m having trouble receiving RTCM/NMEA messages from my ESP32. I can send commands via YAT but nothing in return including usual GNSS data. I’m trying to rule out the version as the issue for my problem. Thank you!
You have to verify that there is connection between esp32 and the module, this with any tcp_client…
also check the switch of mozihao are both left side for uart/ttl as @splee recommendation:LG290P: data via uart - #40 by splee
satrack versions do not affect nmea (protocol) sentences.
Post a check list to verify hw & sw…
ESP32 and Module are connected and switches on my board are sent to TTL direction. I also can confirm the connection to from Satrack to ESP32. No incoming data whatsoever.
So do a check list:
Restore module to default (rover mode)
$PAIR382,1*2E → Test command for lock system sleep enabled
$PAIR003*39 → power off GNSS system
$PAIR514*3A Clear the current configuration and restore the default settings set via $PAIR
$PAIR512*3C clear all data
$PQTMRESTOREPAR*13 # restore $PQTM params to default
$PQTMSAVEPAR*5A
$PAIR023*3B reboot module
$PQTMCFGRCVRMODE,W,1*2A # set receiver to rover mode
$PQTMCFGRCVRMODE,R*32 ask & get result
$PQTMSAVEPAR*5A
$PAIR023*3B reboot module
find ip address of esp32 and so on…pc satrac must be on same lan.
I succeeded to execute all the commands provided but still no luck. The strange part about the entire thing is that I can send a command via Telnet but the esp32 isn’t forwarding the data via telnet.
I think even if esp32 is connected to tcp/ip: 10.192.169.202 to port: 23 ,esp32 has no connections with the module LC29H ; it may be an behaviour like here LC29HEA UART i/o pin drive capability?
maybe try another firmware on the esp32…
Hey, good news! The post you recommended was the solution. This is what I posted:
I’ll be, it worked. My ESP32 is finally receiving and forwarding data through my server socket. For those that want to know what I did, I soldered a jumper cable from one end of the resistor to the other end. I’ll be doing this to my LC29HEA module as well.
Thank you for your time and pointing me in the right direction! 
Hello Sir,
A few questions for you, do you also work with modules from Allystar? How are they comparible to other competing modules? Which have you found to be the best for your expectations and expertise?
I appreciate your feedback and thanks for you assitance.
As for the dual frequency rtk modules I can say that they are equivalent, it is important to equip them with a good antenna… triple or quadruple band receivers have an extra gear that facilitates the solution of the carrier phase ambiguity in a few seconds.
Quectel offers the LG290P Multi band modules, what model does allystar offer? I can’t seem to reach the website due to a firewall from the US. I get very limited information.
Is quantity of bands is all I look for when it comes to antennas or would you suggest other features on it? I’m speaking in general terms. If you like you can break it down by application.
