Thank you!! This solved my problem. I think when I was connecting the SIM800L V2 directly to Arduino, it was unable to get the 2A current it needs. Now I am using a 9V battery with a DC DC Buck converter (LM2596) and adjusted its output voltage to 5V. Also, another thing which I had to change was I had to change the SIM I was using from JIO to Airtel (I am from India). Apparently, JIO is not supported by the SIM800L V2 as it works on networks which support 2G fallback.
I tried powering up the module with 5v from buck booster. I am using 9v 2A rated adapter power source..my module's ring led is on for 10 secs while the net led blinks every 1 sec. Then both the LEDs go off for 2 sec..this process repeats..kindly help me to trouble shoot. please
@@rakshitabaadkar8355 Hi Rakshita, I had faced this issue as well. The sim800l v2 actually needs a lot of current while trying to get or send a signal. If it does not get that, it resets and starts the process again. Can you please use a multimeter and check the current being passed in the circuit?
Hello, i have a question, can i use a step up module instead of a step down? I intend to use the arduino for powering up the sim800l v2 since external power supplies can be quite pricey here in our place. If not, can you let me know what module you used to connect the charger to the breadboard(the black charger port thingy)? I already have LM2596, and i'm just torn what to buy, the step up or the charger port.
@@teguhgumilar6868 ok, I believe it is better to get a better module, to be honest. I spent a week trying it, but it did not work well. There were power and other issues. A good thing happened just now: the module burned due to the wrong current and voltage I gave it, haha. So eventually, something happened that directed me to discard it. So would you mind recommending me some modules (not expensive) not like this module sim800l drove me crazy? Thanks
@@teguhgumilar6868 Good news, SIM800L burned :D Would you mind please suggest me some alternative and works well smoothly without drinking 100 coffee trying to setup the module with my esp32 please? This SIM800L I hated it and it is very boring to work with.
@@altarazisultan It's very old module, just buy TTGO T-Call ESP32 and be focused on the sensors rather than working hours for SIM800L v2... The signal is sometimes not stable too. Try to use new module (technology) which is more practical and stable
Sleep mode: 0.7 mA (typical) Idle mode: 5 mA (typical) Active mode (GSM data transmission): 200-400 mA (typical) Active mode (GPRS data transmission): 300-800 mA (typical)
saya sudah coba tetapi kenapa masih ga bsa ya kak? saya udh pakai adaptor dari charger hp dengan kabel sependek mungkin, tapi dalam beberapa detik, tetap ngereset modul gsmnya
Kalo masih belum berhasil , coba gabungin 2 charger HP pararelin, positive ke positive negaitf ke negatif, yg saya berhasil juga, pake kartu yg sinyalnya bagus gan, telcomsyel mungkin... terus coba karena saya juga berhasil nya ga sekali wkwk
harus d coba bang. Saya pernah juga pake yg charger Hypo nymp dan bisa, dan kabelnya kalo bisa sependek mungkin untuk efektifitas transmisi listriknya.
Hi, I think so, as long as you use the same Arduino board and SIM800L v2 and make sure that your SIM800L v2 get enough current from the adaptor or battery
O pantess sim800l v2 saya kedip cepat teruss nyari signal gx dapat2 mungkin kurang tegangan bag.. Soalnya saya langsung dari arduino..selain pakai step down Ada lagi yg lain gx bang solusinya

Can I use two 3.7V 18650 rechargeable batteries as external power supply?
if you see the specification, it has to use 5V not 3.7V. So I guess can not be used
@teguhgumilar6868 I will use a LM2596 DC-DC !
@@nouhayla6156 make sure the the SIM800L is 5v and better has 2A current. You have to check its output first before buying & using it

Hi as long as it can supply enough current to the module it should not be a problem, check its output specification
For esp32 instead of Arduino, is this still the only solution since the module currently could not find any network or recognised anything around?
maybe use better GSM module or use ESP32 with GSM module built in such as TTGO T-Call ESP32.

good day hoping you can answer my question and problems can sim800l V2 support 4g or 5g sim
sim800L v2 is for data communication using sms if you want to use internet you can use Esp8266 or esp32
my sim800l V2 was always blinking can u help me?
you can use 4G SIM if your network provider supports 2G Network

Jadi harus pake step down ya bang
