Hi, I am using CYBT-343026-10 module with external MCU. communicating successfully using HCI command. But I have some doubt.
1. I am getting response but after sending the same reset command 4-5 times and sometimes I get 04 0E 04 01 03 0C 0C. Instead of getting 00 as my last byte I am getting 0C Which is command disallowed.
2. Here how i send commands.
RTS = 0;
//hardware reset
BT_RESET = 0;
delay(1000);
BT_RESET = 1;
//THEN I SEND RESET COMMAND
01 03 0C 00
//CHANGE LOCAL NAME
01 13 0C 04 XYZT
// SCAN ENABLE COMMAND
01 1A 0C 01 03
//WIRTE PAIRING MODE TO ENABLE THE PAIRING MODE
01 56 0C 01 01
I get correct response, but when i try to pair the BLE with my phone it doesnt connect and even sometimes it asked for 16-bit pin.
Do i need to send some other commands too? or i need to get out of command state of the module?
3. Can i used HCI uart to run further application?
Thank you.

If you are going to use the module to transfer data with BLE or SPP, I suggest you to use the EZ-Serial FW. It is a UART-BLE bridge and easy to use. You just need to send some AT command through the PUART. Please take a look at the introduction for the EZ-Serial FW:

If you want to use the HCI command in your application, you need to run a bluetooth stack on your host MCU which may need more development.
