Beta Version for the OTA DFU for Windows. Is necessary a BLE 4.0 interface and Win 10.
The app is not already signed. Is necessary to allow the developer mode on the windows settings.
Console Windows app to upload an application via BLE on nRF52 MCU that has the DFU Service installed.
It works only on Windows versions >= 10 and a PC with a Bluetooth 4.0 interface
Usage: OTADfu_Console.exe [help] or [scan] or [update -f <bin_file> -d <dat_file> -a <device_address>] or [update -z <zip_file> -a <device_address>]
OTA DFU update application for nrf5x MCUs. Visit https://github.com/astronomer80/nrf52_bledfu_win for more information
Here a list of commands available:
help: Show this help
scan: Scan BLE devices already paired with Windows Settings
update -f < bin_file > -d < dat_file > -a <device_address>. bin_file is the file generated from the Arduino IDE. dat_file is the init packet generated by nrfutil application. device_address: is the address of the device returned using 'scan' command.
update -z < zip_file > -a <device_address>. zip_file is the archive generated by nrfutil application. device_address: is the address of the device returned using 'scan' command.
update -h < hex_file/bin_file > -a <device_address>. hex_file or the bin_file is generated by the Arduino IDE. nrfutil application generates the zip archive. device_address: is the address of the device returned using 'scan' command.
Optional parameter -v: Verbose mode. Adding this parameter as last shows more information during the update procedure.
Example:
OTADfu_Console.exe help
OTADfu_Console.exe scan
OTADfu_Console.exe update -z application.zip -a xxxxxxx
OTADfu_Console.exe update -f application.bin -d application.dat -a xxxxxxx
OTADfu_Console.exe update -h application.bin -a xxxxxxx -v
where xxxxxxx is the device address returned by scan command
DFU Procedure performed by this application:
1)Send 'START DFU' opcode + Application Command (0x0104)
2)Send the image size
3)Send 'INIT DFU' Command (0x0200): Called in the controlPoint_CalueChanged event invoked when the BLE device replies after sending the image size.
4)Transmit the Init image (The file DAT content)
5)Send 'INIT DFU' + Complete Command (0x0201)
6)Send packet receipt notification interval (currently 10)
7)Send 'RECEIVE FIRMWARE IMAGE' command to set DFU in firmware receive state. (0x0300)
8)Send bin array contents as a series of packets (burst mode). Each segment is pkt_payload_size bytes long. For every packet send, wait for notification.
9)Send Validate Command (0x0400)
10)Send Activate and Reset Command (0x0500)
