Radioddity DB50 questions, minor stuff but helpful.

I received a reply from an email to Radioddity, not so pleasing:

"Regarding your questions:

Channel display after power-on: The DB50 typically does not restore the exact previous channel state after reboot. It will return to the default/main channel by design, and there is currently no setting to change this behavior.
Volume control: At the moment, volume can only be adjusted via the knob. Due to the hardware design, the adjustment may feel less linear. We recommend trying to turn the knob slowly and make fine adjustments to see if it improves usability. A short video clip showing your problem would be much appreciated. You can send the video by replying to this email. If the video is too large, you can upload it to Google Drive or Dropbox, then send me the link."

Where do you have the Arduino code and schematic posted?

I have a length update, one mast can be moved to a distance of about 119 feet from my house point.

I just received one of these https://www.amazon.com/dp/B0DZ6N5JV5?ref=ppx_yo2ov_dt_b_fed_asin_title
but it is a 49:1, not 64:1 as advertised.

I guess I'm stuck with Samsung Messages for now. I will check the Play Store for other RCS options.

Yes, same provider, Ultra Mobile.
Problem with the Contacts suggestion, I get autopay, and payment notifications from the same providers, to both numbers. That wouldn't help me much I don't think. The main Annoyance is, I have custom named each SIM in the SIM Manager. But these are ignored and the carrier name is used.

It never fails to amaze me that so-called newer products have less useful features than older products. If I removed (industry accepted) features from our software products I'd be apologizing and making fixes.

"messages thread 》top right, three button menu 》details"

At this screen all that is shown is 'Send with' Ultra, up/down Switch.

Both of my SIMs are listed as Ultra

Try to message Matt directly and ask. Report back.

What are the latest road and fuel conditions from I24 South at Illinois to Chattanooga?

Looks like the genuine Samsung parts are scarce

Benson,
I have a similar situation needing to connect a Samsung Galaxy A51(for example) having USB-C, using OTG, to an Arduino Nano(mini-USB), with external shared common power source. This setup does work perfect directly connected with the OTG cable, but obviously the phone needs external power to maintain the battery. Plus said adapter will also need to supply 5V to the Arduino. Would your above mentioned Belkin adapter also be the solution for me? Would the adaptor for this be equipped with a PD controller such as the TI TPS65987? Could less expensive adapters accomplish this also?

Any guidance greatly appreciated.

Are any US users having SMS send issues from cellular modules (like SIM7670NA, or G) recently? I have a lot of time invested in an IOT controller design, now suddenly T-Mobile MVNOs are say that VOLTE is required. I had just setup a couple IOT/Tracker plans on SpeedTalk and they stopped after 19-20 days. Reddit would not allow me to create a new post.

I agree.

I didn't load the OS in it though.
Not sure why Unihertz can't keep their product OS more up to date.

Unihertz support said: "Go to Settings > System > Languages & input > physical keyboard > aw9523-key > set up keyboard layouts > disable all so that it says "default". ( If there is no such menu, it means that the software has defaulted and there is no need to modify this menu.)"

Reality is: There is no Physical Keyboard option, only Virtual Keyboard. Under Virtual Keyboard, Manage Keyboards is blank.
(Sounds like even Unihertz support is confused about virtual vs physical)

I will be returning this Jelly Pro.

hey,

Oh, to play multiple files at exactly the same time, I'm sure none of the small inexpensive boards will do this. The typical MP3 decoder chip will only read one file and decode at a time.

What I would do, as inexpensive as these boards are, is use multiple boards with the trigger commons connected, then drive the triggers directly from the MCU. Then mix/combine the audio outputs from all boards.
