[nRF51822] How to demostarte DFU OTA in nRF6310?

[Jeffery]

Hi I tried DFU OTA in nRF6310 board as SDK document guided but it cannot work.

• Boot loader is from SDK5.0.0 device_firmware_updates project..
• SoftDev is v6.0.0.
• Nordic Apps is iOS7 or Android nRF_Loader
• OTA download built-in “ble_app_hrs” or "ble_app_rscs"

Steps:

1. Erase all flash (nRF51822] by nRFgo

2. Program SoftDev v6.0.0 by nRFgo

3. Compile SDK5.0.0 DFU project(OTA) and program to nRF51822.

4. Connect it to Apps nRF_Loader

5. Select updated file “ble_app_hrs” or "ble_app_rscs"

6. Press Upload to start DFU.

   Uploading process was successful in nRF_Loader Apps. But, the expected application didn't work. Ialso used Master Control panel to discover it. Master control panel cannot find the device. Anythig is wrong? Thanks

Hi Wang,

The Softdevice v6.0 and SDK v5.x was released recently, after the release of the the nRF Loader app.

The example that included in the app was from SDK v4.x and could only run with Softdevice v5.x.

You would need to use a new hex file from a SDK v5.x project then convert it to .bin file and upload it to the iOS device.

Or another solution is to use bootloader from SDK v4.x and Softdevice v5.x.
