great project , thank
thank bro !
can we use SIM800L as a standalone in this module ???
What are the pins of SIM800L in this module ?
Hi Cytron, can you share some ideas on ESP32 TTGO SIM800L footprint library for Eagle CAD?
Salam.. nak tanya..utk ttgo tcall ni xda breadboard utk dia ka? Sbb try letak kt breadboard 5.5cm xda space utk taruk pin lain..ngam² dia ambil
hey bro is the board type esp dev works for this module ? .
sir if I want to operate with both normal SMS and gsm data then what should I do ?
buenas tardes puedo hacerte una sugerencia de video como hacer que una placa ttgo esp32 sim800l sea un access point o tramita wifi para que se conecte otros placa esp32
Please help.
I have a TTGO T-Call ESP32 SIM800L base plate.
I checked it and the SIM800L responds to AT commands.
However, the program does not meet the condition
if (sim800l.available ()) {....} - do not enter
What could be the reason?
Please help.
Maybe the SIM800L module must be prepared with AT comment?
Hi. can i control the relay by Call. to turn on from one number and turn off from another
Hi, your tutorial is very helpful, but give me PLS a hint on how to change the text of an SMS. Your code has "Relay is activated." and I would like to send a string of constant phrases and variable values. Whatever I type in here, I always have a compilation error. Can you give an example of how to do this?
// Send SMS for status
if (!sim800l.sendSMS(callerIDbuffer, "Relay is activated.")) {...
need it for example
String SMStxt = String("Poziom wody:") + poziomWody + String("cm Trend:")+ trend+ String("Napiecie:")+ volty + String("V Temperatura:")+ temperatureC+ String("'C ") ;
then
..sendSMS(callerIDbuffer, SMStxt))....
but it doesn't work unfortunately
Bro nak tanya untuk Gsm module 800L boleh kita guna sim digi? Tolong jawab
Thanks for sharing. Hope to see the video about this unit sim800l esp that can be sending data into thingspeak or adafruit io account tuan. Tq again for sharing
Do you know i can connect it with raspberry pi 4 b+ ? i want to send sms
Greetings, thanks for the tutorial.
Can I connect two 18650 lithium batteries in parallel to the module (TTGO T-Call ESP32 SIM800L)? Can the power manager supply enough current to charge the two batteries in parallel?
i.imgur.com/qYNEdKA.png I too have the same question
Salam bro, mcmne nak connect ke internet thorugh sim card pakai board ni
Saya mau bertanya. Kalau misalkan saya gubungkan komunikasinya antara gprs dengan wifi dengan tujuan kalau misalkan device tidak bisa mendeteksi wifi, sinyal yang didapatkan dari gprs daripada simcard atau sebaliknya. Kira kira hal macam itu bisa kah?
BTW, saya dari Indonesia. Maaf kalau bahasanya beda sedikit.
Asslm, bagaimana nk buat phone call notification guna board ni? Saya guna apps blynk
Ada error masa compile..sbb apa eh
error: stray '\223' in program
C:\Users\User\Documents\Arduino\1\1.ino: In function 'void loop()':
1:66:20: error: expected ')' before 'prevMillis'
if (millis() - prevMillis > interval) {
Hallo...
I didn't understund why it's doesn't work.
It does not turn on the GPS LEDs.
With other source it works but only with a send library.
Maybe they changed library?
Or other?
Thanks

Saye ikut tutorial ni, saat menerima sms berungsi dan muncul di serial.monitor nye, tapi saat mengirim sms sendsms nye, selalu gagal, padahal saye hanya copy paste, tidak ade modif ape" masih source code ny
Hi, excellent video tks for sharing ,how can i get to instead message make me a call
simcard provider?
can you help me?
Ada possibilty tak kalau saya nak modify coding project ni dengan tambah function push button untuk tujuan bila button itu ditekan, akan ada sms diterima pada telefon?
Ya possible. Ianya boleh dilakukan.
I have a problème I think it's my Sim card because she have a pin mode and when I send sms the esp don't react
Please help me!
Hi, you may drop an email to support@cytron.io for technical assistance. Thanks :)
GOT IT TO WORK FINALLY
how to set it to do the command only when a specific number texts?
You can check the sample program line 118, it print "callerIDbuffer". Try to play with that variable. 😊
Este código es incompleto, no solicita el número de teléfono que envía el mensaje ni el sim code, por lo tanto no puede utilizarse como esta.
Hey fantastic project can you build a GPS system on this i got it a day ago in india
This board don't have GPS. You may need to mount external GPS board for this application.
@@idriszmy ya bro thas what i am saying can you help me doing that thing it will be lot helpful
@@RideIndiaRide Oh sorry, I'm not doing custom project. We just share tutorials for other to try and learn. You can search for freelancer for that kind of job. :)
Bang yang belum solder itu apa bang di board selain pin header ?
Antenna ke? Itu tak perlu solder, pasang saja.
Hey,
any Ideas why reading is not works if my SMS iss longer then 43 chars?
Oh I never test that. Maybe it is because of the library.
@@idriszmy Mhhh, maybe. In the src I did not found anything about it. :(
@@MilchbarMC FYI, the SMS data will be stored in the smsBuffer (line 79), and it print the message at line 123-126.
@@idriszmy Jep I See. Will debugging a little bit ;)
esp32 nie boleh pkai untuk tracking location tak?
boleh. connect pakai apps blynk lebih mudah
@@nurulainaa2318 tumpang tanya macam mana nak buat phone call notification guna board ni?
Do i need to solder the antenna ?
No need for that, only place it on the antenna port.
@@cytrontech Mine doesn't allow me to do it. That's why i asked.
Boleh guna banyak rrlay kah
Muhammad Arief boleh. Berapa banyak tu?
why is description and everything in english but you speak chiccy nuggies language?
Hi, thanks for the feedback. Anyway we have put the English subtitle in this video. Hope this helps.
*The language that I speak is Malay and it is from Malaysia. :)
Can I use 4G Sim card?
when i use 4g sim, my apn setup still using 3g
@@nurulainaa2318 does it work with 3g signals ..i saw it uses only 2g .
Bukannya Sim800l dh x boleh guna ke?
Kenapa tak boleh guna ya? Negara yang masih support 2G, boleh guna, dan Malaysia masih support 2G.
Rasanya module yg Cytron guna ni dh invented. Jadi, stable. Kalau guna module jenis lama, dh x boleh guna dh
@@samalifgaming3946 oh yeke? Ok terima kasih info. 👍
Starts if English then.......
Keren.. ada yg pernah coba berhasil..?? Kasih tau y..? Mau coba ni,, soalnya sering ku ikutin tutor dri internet.. gagal.. l. sayang dh beli hardwarenya..
Jangan pernah kecewa gagal, cuba dan terus cuba untuk berjaya. Tambahan sekarang harga hardware tidaklah begitu mahal kalau mahu dibandingkan dengan ilmunya.
