BR/EDR Connection Fail

[carlosfinocchia]

I am working with a CYBT-483056-EVAL board and trying to connect to a Bluetooth classic device.  I am using a serial terminal to send commands to the eval board via the USB port.  I am unable to connect to a device. I tried connecting the first time (To pair) and the second time (To connect) and I'm not successful. I get error 500 and then error 1600. I don't know what those mean or how to fix it.

##### FACTORY DEFAULT (I want to start clean)

/RFAC
@R,000B,/RFAC,0000
@E,0005,RFAC
@E,0040,BOOT,E=01000A1B,S=02072276,P=0100,H=E8,C=00,A=EE596D3A570C,T=01
@E,000E,ASC,S=03,R=01

##### QUERY BONDS (No bonds at this time)

/QB
@R,000E,/QB,0000,C=00

##### CONNECT USING SPP (Error 500 is "GAP error category" What does that means?)

/BTC,A=886B0F5114C7,P=00
@R,000A,/BTC,0000
@E,001F,BTCON,C=01,A=886B0F5114C7,B=00
@E,000F,PR,C=01,R=0000
@E,000E,ENC,C=01,S=01
@E,0020,BTCF,C=00,A=886B0F5114C7,R=EEEE
@E,001F,BTPDIS,C=00,P=00,H=0003,R=0000
@E,0012,BTDIS,C=01,R=0500

##### QUERY BONDS AGAIN (Now we can see a bond to the right device Address)

/QB
@R,000E,/QB,0000,C=01
@E,0020,B,C=00,A=886B0F5114C7,T=00,D=01

##### CONNECT AGAIN AS PER DATA SHEET (Again error 500?)

/BTC,A=886B0F5114C7,P=00
@R,000A,/BTC,0000
@E,001F,BTCON,C=01,A=886B0F5114C7,B=00
@E,000E,ENC,C=01,S=01
@E,0020,BTCF,C=00,A=886B0F5114C7,R=EEEE
@E,001F,BTPDIS,C=00,P=00,H=0001,R=0000
@E,0012,BTDIS,C=01,R=0500

##### TRY AGAIN TO CONNECT (Again error 500?)

/BTC,A=886B0F5114C7,P=00
@R,000A,/BTC,0000
@E,001F,BTCON,C=01,A=886B0F5114C7,B=00
@E,000E,ENC,C=01,S=01
@E,0020,BTCF,C=00,A=886B0F5114C7,R=EEEE
@E,001F,BTPDIS,C=00,P=00,H=0001,R=0000
@E,0012,BTDIS,C=01,R=0500

##### TRY AGAIN TO CONNECT (now the error is 1600 and there is nothing in documentation about this error)

/BTC,A=886B0F5114C7,P=00
@R,000A,/BTC,0000
@E,001F,BTCON,C=01,A=886B0F5114C7,B=00
@E,0012,BTDIS,C=01,R=1600

##### QUERY BONDS AGAIN

/QB
@R,000E,/QB,0000,C=01
@E,0020,B,C=00,A=886B0F5114C7,T=00,D=01

@PratikshaV Yes that is the same user guide I'm using as reference. Thank you, I have tried pretty much everything in my knowledge and I'm not able to stablish connection.

@PratikshaV Any luck testing this? We really need support on this.

Hi @carlosfinocchia 

Sorry for the delayed response..

Please make sure both the devices are disconnected before reconnecting once again. Also please can you share me the detailed logs. 

Thanks & Regards

@PratikshaV Yes both devices are disconnected before reconnection, What do you mean by "Detailed logs"? What I shared is everything I get on the terminal. (minus the comments i made starting with the "#####")
