If you got a fake HC12, and range is super low, here is the fix. Just solder the registers as shown by the author

I love your work! Thanks a lot
Another really good video, thanks
Hi,
Nice tutorial!
Please make a video on interfacing OV7670 Camera Module with STM32.
Thanks!
Nice Video.. Can you also do an example how a CAN-Bus communication between two STM32 controller works.. thnx
can you please make a tutorial, BlueTooth communication with mesh networking, please. I am a great fan of this channel. Thanks for your valuable work
well done :)
Nice job. Thanks. What terminal do you use?
Hercules
thank you,
please make a tutorial for OV7670 CAMERA WITH STM32
@ControlletsTech, Hi sir! I have one good hc 12 module which is responding on AT command. But others are not even working on AT command. How to fix this? Pls help!
Hc12 module supports mesh network?
If yes can you make a video plz
Hello ! Sir ! A lot of knowles in your video thanks. I have some Question "Can config bluetooth module without AT command?". Sush as I sent my project to my friend and he want to change bluetooth password but he can't under stand MCU or someting like that. and Thanks again.
No you can't... And you don't need mcu to use AT commands in bluetooth. Just connect to PC using ftdi and use the AT commands directly from the computer
how can we get the original one cause the site is in chinese
Hello ! Thanks you for this video. I can create video "Interface Nrf24L01"
Can u share the video link plz
I am not able to send faster than 500ms delay on si4463. What to do?
Data rate might be limited from the HC12. Use AT commands and try to increase it.
@@ControllersTech I am doing internship and they have given me a small pcb which have Si4463 chip. I have to use stm32 blue pill spi communication.
I tried but the tx fifo of chip overflows and give error if the delay is more than 500ms.
I also saw the GitHub Library for stm8 which is used in HC12 module. In that code too their is 500ms delay.
In another Arduino Library they were taking 500ms delay
The max size of fifo is 64bytes so I don't know how it can send higher bytes per sec. Max speed on net is 1Mbps.
Is it possible to reach that speed? Even 10kbps will do. If possible with HC12 then I will try Bare-metal and HAL for sending commands.
Thanks
Sir can you please tell me that how we can get the Password and mac address of HC12 as we get it in HC05? and how we make one as master and the other as slave ? HC12 datasheet does not have AT commands of ROLE, ADDR and BIND? HOW we set its name and password? please answer
HC12 is not a bluetooth device. It's a radio transceiver, which works at 433MHz.
@@ControllersTech thankyou sir for your reply. Is there any long range bluetooth module 100meter range?
I don't think so. Even the 5.0 have 40m i guess.
If you want 100m range then radio devices are the best options for you.
@@ControllersTech thankyou very much sir , for your replies in short time.
How can i use hc-12 with arduino using python language??
Just use it how you use a serial device. I mean how to write data to the serial monitor..
@@ControllersTech can i use it to send data when i run python code directly?
Don't know about python. But if you can print on serial monitor, then you can use this too
