STM8S003F3 used in HC12 module with Si4463 transceiver

[kannannatesh]

Dear Friends,

i am working with HC-12 module that have inbuilt STM8S003F3 Microcontroller with Si4463 Transceiver module. that works fine at data transmission. But i am trying to upload Arduino Sketch through HC12 Wirelessly for a long distance. here i need data ready pin (DTR) for enable the bootloader for sketch uploading but HC12 have only tx/rx and set pin. i search google about HC-12 details that shows some 5 AT commands and wire connections for serial data transmission so i can't get clear idea. that's why i ask question here.

My Question: the STM8S003F3 microcontroller have any pin like a DTR or not.

If anybody have any suggestion or solution about my problem please let me know,

Thank you

with regards

I am using the source file for HC-12 module from github https://github.com/fademike/STM8S003_AND_SI4463. it was missing AT commands.I tried to modify the code for HC12 Module. now it is not working. can you please send hex file if you retrieved it
