i took a code from chatgpt for my bluetooth and when i UPLOAD it keeps uploading then it gives me errors :- avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer تعذر الرفع: خطا اثناء الرفع exit status 1avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer تعذر الرفع: خطا اثناء الرفع exit status 1i took a code from chatgpt for my bluetooth and when i UPLOAD it keeps uploading then it gives me errors :- avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer تعذر الرفع: خطا اثناء الرفع exit status 1avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer تعذر الرفع: خطا اثناء الرفع exit status 1 a1f0fcda-dfcb-4a28-9b4a-a18e6c35a5fa

The flashing of the HCxx board is not influenced by the code you are uploading.

I have used these HCxx boards with succes for a long time. Checkout ESP8266Station You may have swapped the TX<=>RX connection. It depends on how you setup your board. In the link you find an example for connecting them to D2 (TxD) and D3 (RxD) In the past I made my own level converter boards but now I buy these kind of boards.

Here you find a complete instruction to setup ramps and connecting to bluetooth
