How to multiple times update program in secure OTA

Hi,

I had Completed secure OTA in my custom board (RL nRf51822 A1).

We have to PCBs. 1). Old Design 2). New Design

1). Old Design: We have connected relay on pin(p6) through transistor doide circuit(BC457 and 1N4007). In that secure OTA worked successfully.

2). New Design: We have connected relay on pin(p18) through transistor doide circuit(BC457 and 1N4007). In that secure OTA is not working.

The transferred process has been completed successfully but not transferred actually. But if i remove transistor than everythings is works properly.

How can i solve it?

No, this is a known issue that does not affect the transfer. It has been fixed in in the upcoming SDK release where we are pulling the buttonless example out of experimental.

Hi,

Thank you.

After adding the line "char_md.char_props.write = 1;" in ble_dfu.c file. I have done successfully secure OTA multiple times.

But when i perform the DFU second time, one more tab opened by itself "DFUtarg" in my mobile application. My application transferred successfully.

so, Is there any problem in transfer process?

Examining the log I can see that you never enter the bootloader on the second attempt, you're only writting to the Experimental Buttonless Characteristic. Have you added the missing write property in the buttonless example which is described in this answer.

Im not asking if you are using breakpoints, I am asking if you can start a debug session and set a breakpoint according to the instructions in my previous comment.

Could you start a debug session in the bootloader after you have performed the first DFU, press run without setting any breakpoints, the bootloader shoudl then start the application. Now set a breakpoint in the bootloaders main and then start a DFU and see if you hit this breakpoint.

Yes, Buttonless DFU service added in my application.

No, I am not getting any error but update stuck on waiting Boot loader.

The command which i used for generate zip for first time is nrfutil pkg generate --hw-version 51 --application-version 1 --application nrf51422_xxac.hex --sd-req 0x87 --key-file private.key nilesh.zip

Then, just change the advertisement name and using same private key and public key for generate zip second time and command is nrfutil pkg generate --hw-version 51 --application-version 1 --application nrf51422_xxac.hex --sd-req 0x87 --key-file private.key nilesh_1.zip or once tried with change application version 2.

I am using s130_v2.0.1 soft device.

Do you get a time out error on the second try? Could you post the nrfutil command that you're using to create the zip packet?

Yes, I am generating images using nrfutil with a same private/public key pair which used in first time. I am not getting any error when update the second time but its stuck on "starting Boot loader" message in mobile application.

In the Buttonless DFU example file of the SDK, mostly DFU setting are available and i do for the trigger bootloader multiple times DFU "#define IS_SRVC_CHANGED_CHARACT_PRESENT 1".

If there any other setting is required for that?

Could you describe in detail what steps you have done? Do you get an error during the DFU process? Are you using the test images for the SDK or are you generating images using nrfutil with a private/public key pair?
