DTDS-622C MEVB Lora modam programing

Hai iam Sarath Santhosh
Can anyone please help me out by giving the details about how to program this device(DTDS-622-MEVB) for sending and receive data, I also want to know about how the data packets are handled. This is for a project related to smart metering I just want to setup a gateway for that.
I want to know about the details of how I can set up the gateway.! -

Hi @sarathslab ,
Thanks for asking on MakerGram Community Forum!
Is this is the one you're using?
-
@swalahamani yes
-
@sarathslab Did you check the documentation?
If not please check those first and post the issues or blockers you're facing while doing it here.

@zainmuhammed @salmanfaris You may be able to help with this.

@sarathslab why your are choosing this perticular LoRa module, can you please elaborate your use case. Personally I don't have experience with this module. When i go through the details of this hardware find like this is a UART device and so you can communicate by using the AT comments. And this will be available on the datasheet I guess. Also if you don't want to use this perticular module I suggest sx1276 or LoRa E5 from Seeedstudio. And by using this you can able to connect with helium network or things network. If you want to know more about this I think Salman can help.

@binishmatheww All the best. Let us know if you need any help.

@salmanfaris thanks a lot.

@binishmatheww There will be a single device, but I can't find one for now that has both GPS, GSM, BLE and USB Support.

Also, can we have all these data transfer modes in a single module?
You can make the priority and depending on that it can switch different modes.
@binishmatheww said in I need help in making a GPS module:
Transfer the data via Bluetooth if is connected.
This can be achieved with BLE transfer.
@binishmatheww said in I need help in making a GPS module:
Transfer the data via a USB cable if it is plugged in.
It can be achieved via Serial communication or USB HID profile.
@binishmatheww said in I need help in making a GPS module:
Transfer the data over the internet.
here, we can route the data to the cloud over the phone or directly to the cloud via a GSM module or WiFi. I think it will be overkill if we use an external modem, better to cache the data and push to the cloud via phone and BLE if the live data is not needed.

@salmanfaris thanks for the reply Salman
Transfer the data via Bluetooth if is connected. Transfer the data via a USB cable if it is plugged in. Transfer the data over the internet.
.
Is it difficult to transfer the data via a USB cable instead of Bluetooth?
Also, can we have all these data transfer modes in a single module ?If we have all these modes in a single module, will it increase the processor load ?

Hi @binishmatheww , Welcome to Makergram.
I see you want to build a GPS Logger. For that, you can use any basic GPS module available in the market such as NEO-6M GPS Module or any from the list here.
After that, you need to choose a microcontroller, which can communicate with the GPS module read the GPS and translate the NMEA (data format for GPS packets) to a more usable format (you can do the post-processing in the phone too).
Then you can send the data to hone via BLE, for this you can use a BLE-supported microcontroller or use a standalone BLE co-processor. My suggestion is to go with esp32 as it has BLE support and other cores can be used for the GPS data acquisition. To do the post-processing and other things you can do with the mobile app.
You can split the project into different parts.
GPS Data Acquisition. (You can use Arduino IDE + ESP32/Pico W + GPS module of your choice) GPS data translation (There will be Arduino lib which can make the translation easier) Send Data to the mobile app via BLE (Arduino IDE + ESP32/Pico W + BLE LIB + Mobile application).Hope you get an idea, please check and let us know. Happy building.
