Hi all,
This is a real newbie for Nordic devices.
I'm testing the usbd-ble-uart with an nRF52840 dongle(PCA10059) as following features.
- Develop under nRF5 SDK version 17.1.1.
- Using soft device 1.4.0
- firmware download with the built-in DFU bootloader
It's working fine. However I found 2 dongles(HolyIOT 21017/17120) for applying into our real product.
since both of them have plastic cases and antenna.
I tried to download the hex file of the PCA10059.
The "nRF52 SDFU USB" was running when I inserted Holy-IOT YJ-17120 into the USB slot.
The programmer in the nRF connect said
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
"Failed with exit code 1. One or more program tasks failed: * ED6CF1F60BA7: Internal sdfu error: Response failure from packet: DfuResponse { opcode: ObjectExecute, result: ExtError, extended_error: SdVersionFailure, response: None } (Generic) Message: Failed, Internal sdfu error: Response failure from packet: DfuResponse { opcode: ObjectExecute, result: ExtError, extended_error: SdVersionFailure, response: None }."
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
In case of Holy-IOT YJ-21017, my hex file could be flashed successfully.
But it didn't at all. no LED flicking and I couldn't find the USB device at the Device Manager.
I wonder both Holy-IOT YJ-17120 and YJ-21017 are compatible with the nRF52840 dongle(PCA10059)
Any hint should be really appreciated.
Best regards,
H, Kim
