Re: Auto Start Node server on Boot

If I understand you correctly, then your log on the PHL shows (1) that your nodejs app has actually started, and (2) that your nodejs app reacts to your connection by logging "Cannot get /". If this is not the reaction that you want, then you need to fix this inside your custom nodejs app,...

Re: Time and Calender Settings

I am generating some files using the timestamp but it looks like PHL's calender is wrong. As nmichael says, the PHL does not have real-time-clock hardware, and therefore cannot keep track of time and date between reboots. Also, its operating system does not connect to the internet on each reboot to...

Re: Serving React App with node-red

Searching for serve web pages with node-red finds a couple of hits that look relevant to your project.

That said, the PHL runs Linux on a 32 bit ARM processor, so any other common technology to serve web pages from Linux can be realized on the PHL, and may be cheaper, CPU-wise, than using node-red.

Re: Offline fitting tool

(2speaker_diffNoise_2ch.wav) I cannot find any file with this name in openMHA. I suspect you mean 1speaker_diffNoise_2ch.wav from the 01-dynamic-compression example directory. When peak level is set to 100 dB for this file, then this file contains the following acoustic levels: left channel: 76.9 d...

E.g. if I apply Linear40 rule then I should get output wav file according to that gain rule (40dB gain should get applied) No, this is not the case. Please se...

Re: Offline fitting tool

Thanks for providing more information. Could you please add which audiogram you chose. And then it would be good to concentrate on just one prescription rule, let's say CRvar_NALRP with compression ratio 3, which compresses the dynamic range by the given ratio while it IIRC applies NAL-RP gains at 6...
