nrf52832 OTA over ESB based on SDK17.1.0

Hi everyone: I developed an application based on ESB wireless communication protocol ofr the nRF52832, and I would like to perform an OTA DFU with it. Do you know any example of some over the air FW upgrade of nRF52832 chip via ESB protocol.

SDK is 17.1.0.

Best regards,

Lurn.

I also try to make a script even use your script, but not worked.

I was only used bootloader and mbr.hex without application too.

Is my file too large causing insufficient space? Because the return error is 4.

But my application should be this size, and I can update via nrfutil.

I have no idea about this.

Update:

1. I modify the bootloader addr and size.

due to the bootloader is debug mode, I can't set the address to 0x78000, because if end address is 0x7E000, the size is not enough.

this is my set now.

2. Base the 1. sometime the error like this.

Is this error because the length is not a multiple of 4 bytes?

But I think this packet is the last packte, so i can't decide his size.

Should I need to modify the bootloader? I mean if the target device in DFU mode need some special state?

such as the macro NRF_DFU_SINGLE_BANK_APP_UPDATES is 0 now.

Hi Edvin,

I think the reason is that the UART tx pin of my mast device is floating, causing some unpredictable things.

I set the gpio to PULLUP, and it solved tht problem.

    if (p_config->pselrxd != NRF_UART_PSEL_DISCONNECTED)
    {
        nrf_gpio_cfg_input(p_config->pselrxd, NRF_GPIO_PIN_PULLUP);
    }

But after that I get anoter error.

OK, I was update successfully one time(I think), after I modify the TX pin state, and then, I never success.

The last log shows:

Hi Edvin,

First of all thank you for taking so much time to help me with this problem.

Now I can update successfully although I always get something wrong, but I think the question is on my hardware and the connect way.

I'll start porting it to other devices to test.

Thanks again for your help

Best regards,

Lurn
