Getting "CRC does not match!" in nRF Connect iOS mobile application

Hi Charlie,

Below are the answers for your questions:

DFU for hrs_application_s132.zip works on nRF Connect for Mobile - nordicsemi.com(both iOS and Android) and your SwiftUI mobile application?
Yes, I tested hrs_application_s132.zip on both nRF apps on iOS and Android; and it works perfect.
zip file from your firmware engineer report "CRC Does not match!" on nRF Connect for Mobile - nordicsemi.com(both iOS and Android) and your SwiftUI mobile application?
Correct.
If 1) 2) is correct, can you ask your firmware engineer to share more details on the zip file generation process? so I can repeat the issue on my side to find the cause.
Ok, I will ask them.
CRC check is an important process to make sure your application zip file is not broken during transmission or modified by someone on purpose. You should not avoid CRC check for any reason. Since the library already provides source codes, I suggest you read the source codes to learn details on the DFU process.
Ok, thank you for letting me know. I will check it.

Hi Meet,

Can you confirm the following questions?

1) DFU for hrs_application_s132.zip works on nRF Connect for Mobile - nordicsemi.com(both iOS and Android) and your SwiftUI mobile application?

2) zip file from your firmware engineer report "CRC Does not match!" on nRF Connect for Mobile - nordicsemi.com(both iOS and Android) and your SwiftUI mobile application?

3) If 1) 2) is correct, can you ask your firmware engineer to share more details on the zip file generation process? so I can repeat the issue on my side to find the cause.

4) CRC check is an important process to make sure your application zip file is not broken during transmission or modified by someone on purpose. You should not avoid CRC check for any reason.

Hi Charlie,

I contacted one of our firmware engineer who created the zip file. He said that he used Nordic tool to generate zip file from .bin file.

My iOS SwiftUI application code to initiate DFU process looks like below:

if let dfuZipFileName = dfuZipFileName, let dfuFileURL: URL = Bundle.main.url(forResource: dfuZipFileName, withExtension: "zip") {
    let selectedFirmware = DFUFirmware(urlToZipFile: dfuFileURL)
    // Use the DFUServiceInitializer to initialize the DFU process.
    let dfuServiceInitiator = DFUServiceInitiator().with(firmware: selectedFirmware!)

    dfuServiceInitiator.delegate = self // - to be informed about current state and errors
    dfuServiceInitiator.progressDelegate = self // - to show progress bar
    dfuServiceInitiator.logger = self // - to get log info
    dfuServiceInitiator.packetReceiptNotificationParameter = 1 // default is 12
    dfuServiceInitiator.dataObjectPreparationDelay = 0.3
    dfuServiceController = dfuServiceInitiator.start(target: peripheral)
}

Note: I have also tried dfuServiceInitiator.forceDfu = true, but that also gave same CRC error.

I have some questions:

Does CRC check is mandatory process to initiate DFU process?
Can you explain how the process works of DFU with regards to CRC generation?
I believe that if I am loading a zip file to my BLE sensor, which has a DFU characteristics. Does my sensor generating CRC, is there any chance my sensor's DFU implementation generating wrong CRC?!
Is there any configuration in iOS DFU library where I can disable checking CRC checksum and proceed directly loading DFU?

Hi Meet,

[quote user="Meet"]The process you mentioned to test loading zip file on my nRF50 worked through nRF connect iOS application. It means nRF iOS application is working. Do you have any idea why my zip file giving "CRC Does not match!" error on iOS and same file working on Android nRF app?[/quote]

If the zip file in nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8\examples\dfu\secure_dfu_test_images\ble works on both iOS and Android apps but your zip file gives "CRC Does not match!", shouldn't you check your zip file next step? Can you explain how you build your application based on which sample or document?

Best regards,

Charlie

Hi Charlie,

The process you mentioned to test loading zip file on my nRF50 worked through nRF connect iOS application. It means nRF iOS application is working. Do you have any idea why my zip file giving "CRC Does not match!" error on iOS and same file working on Android nRF app?

Additionally, Android nRF application printing same logs, means same "CRC Does not match!" error. BUT, on the notification bar, the DFU loading progress shows and it does actual DFU loading even though there is CRC error in logs.

I followed your steps, loaded sd_s132...hex using Programmer app on nRF52 DK, and loaded hrs_application_s132.zip using my iPod nRF Connect app, it worked. Below is the log file:

RE: Getting "CRC does not match!" in nRF Connect iOS mobile application

Charlie — Wed, 23 Mar 2022 08:00:53 GMT

The reason is explained here: https://devzone.nordicsemi.com/f/nordic-q-a/83902/part-of-the-hex-regions-are-out-of-the-device-memory-size-from-programmer-v2-2-0/348902#348902

You can continue the process following guidance and check if DFU works.

Best regards,

Charlie

Got the same error with that file: "Part of the HEX regions are out of the device memory size, but you can still proceed write operation".

RE: Getting "CRC does not match!" in nRF Connect iOS mobile application

You can try nRF5_SDK_17.1.0_ddde560\nRF5_SDK_17.1.0_ddde560\examples\dfu\secure_dfu_test_images\ble\nrf52832\sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex.

Unfortunately, I have only this nRF chip device, nRF52DK.

RE: Getting "CRC does not match!" in nRF Connect iOS mobile application

This firmware is traget to nrf52840DK. You are connecting with an nRF52DK.

Thank you, I found it with your help. When I drag and drop that file in Programmer window, it gave me this error shown in below screenshot:

RE: Getting "CRC does not match!" in nRF Connect iOS mobile application

Charlie — Tue, 22 Mar 2022 10:13:06 GMT

It is located in nRF5_SDK_17.1.0_ddde560\nRF5_SDK_17.1.0_ddde560\examples\dfu\secure_dfu_test_images\ble\nrf52840\sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex.

Hi Charlie,

Thanks for your response.

I am new to loading/programming .hex files to my nRF52 chip. I was able to install nRF Desktop tools and also the programmer app on my mac. Also, fixed the JLink error using the SEGGER. Do you know where exactly can I find the .hex file you mentioned?

RE: Getting "CRC does not match!" in nRF Connect iOS mobile application

Hi Meet,

The CRC = 00000000 looks not usual. I am not sure if your ZIP file has any issues.

Following BLE Secure DFU sample, I tested nRF Connect for Mobile on the App Store (apple.com) with the DFU sample images from nRF5_SDK_17.1.0_ddde560\nRF5_SDK_17.1.0_ddde560\examples\dfu\secure_dfu_test_images\ble\nrf52840 on an iPhone 11 and it works without issue. Can you repeat the test?

1. Program sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex with nRF Connect for Desktop->Programmer app.

2. DFU hrs_application_s1xx.zip through iOS nRF Connect app.

Best regards,

Charlie
