N550 default ANT bootloader ANT-WP

[Flemming Jensen]

Hi,

I have just received a bunch of N550 modules and now I want to try and see if it is possible to update the firmware of these devices without using a JTAG.

If I understand the module correctly - these modules ship with the ANT-WP bootloader.

I have the OTAUpdater.exe (OTA Updater) from the N5StarterKitSDK3.00 is this the right tool for this?

And I have the USB dongle from dynastream... www.digikey.com/.../4793274

Does the module just sit and wait for somebody to contact the bootloader or do I have to do something in order for the module to enter bootloader mode?

Am I on the right track?

Hope to hearing from someone with experience with this

Hi,

I'm not familiar with this particular module, but modules are typically shipped blank. One easy way of confirming this is to connect a J-link programmer to the kit and use nRFgo studio to get a visual representation of what's stored in flash:

Otherwise you need to load the ANT stack and bootloader( \nRF5_SDK_11.0.0-2.alpha_bc3f6a0\examples\dfu\experimental_ant_bootloader) with a programmer in order to enable DFU for subsequent uploads. More documentation on the bootloader can be found here in the SDK documentation.
