Nikon S3700 – connection problem

[g_fenton]

My camera gets stuck “Negotiating…..Please wait” after it connects. If I try to rin Airnef, I get the following error:

airnef v1.1 – Wireless transfer of images/movies for Nikon cameras [GPL v3]
Copyright (c) TestCams.com, Time: 11/10/15 09:44:30, Py: 2.7.9, OS: Linux

Connection established to 192.168.0.1:15740
An exception occurred. Here is the stack trace information:

File “<string>”, line 812, in removeLeadingCharsFromStr

I am running this on a Linux PC with Linux Mint kernel 4.3.0 and Cinnamon DE. Any help would be greatly appreciated.

Can you try the same session with logging set to ‘debug’ and paste the resulting log here? Thanks.

I am sorry that it took me so long. I was traveling for work. Per your request:

Thanks. Based on the debug data the S3700 is returning an empty serial number, which airnef doesn’t expect and results in the runtime error. Can you download the airnef source and change removeLeadingCharsFromStr() to the following (‘charPos = 0’ is only change) and then run airnef from the source and see if there are any other issues working with the S3700? Thanks!

def removeLeadingCharsFromStr(str, charsToRemoveSet):
    charPos = 0
    for charPos in xrange(len(str)):
        if str[charPos] not in charsToRemoveSet:
            break;
    return str[charPos:]

Hey! Found this site today, I have tested airnef and get the same error, I also tested the proposed action and get the following errors and wifi is also turned off. Hope this can be solved 🙂

Thanks for the log. The camera is returning an invalid object handle for the parent directory of the camera’s “100NIKON” directory. This violates the MTP specification. To workaround the issue can you try commenting out line 1842 by placing a # at the start of the line. For example:

		#
		# recurse to create MTP objects for the directory tree referenced by this object if we're instructed to do
		# so and this object has a parent dir and no MtpObject exists for the parent already
		#
		if fFindAndCreateAntecendentDirs and mtpObjectInfo.parentObject and MtpObject.getByMtpObjectHandle(mtpObjectInfo.parentObject)==None:
			applog_d("Recursing to get parent dir of \"{:s}\" - objHandle=0x{:08x}, parent=0x{:08x}".format(mtpObjectInfo.filename, objHandle, mtpObjectInfo.parentObject))
#			createMtpObjectFromHandle(mtpObjectInfo.parentObject, createMtpObjectStatsStruct, cachedMtpObjectInfoListDict, fFindAndCreateAntecendentDirs)

Thanks! Seems to work now 🙂 ran out of battery in middle of the test, but so far it looks good! I test more tomorrow 🙂
