SelfOnly Keeps getting set to '1'

Found another bug in /var/www/dashboard/admin/configure.php In making adjustments trying to fix the problem in a previous post, SelfOnly keeps getting set to 1 when I did not explicitly make the change. The configure.php file tries to apply logic to when SelfOnly should be set. It should only be set...

Re: Received a NAK to the SET_CONFIG [SOLVED]

Well, I found the answer to my problem. There is a bug in the Pi-star software that changed DUPLEX from 0 to 1 in /etc/mmdvmhost whenever there is a difference between the Rx and Tx frequency. I suppose someone was thinking that only a person with a duplex board would do this. WRONG!!! Don't need a ...

Re: How to reconnect a YSF room with a linux command line?

You can't do it from the command line unless you're willing to write a script. The parameters are contained in initialization files located in /etc. Change the init file then start the service.

Re: Display corruption?

Well, thank-you for those links. Glad to see you could contribute something. Unfortunately the poor documentation and lack of resources makes it difficult to identify such sources. I'll guarantee you that if you go on Amazon, like most people might, you're likely to get the SSD1106 chip. To be clear...

Received a NAK to the SET_CONFIG

Using Pi-star, I've been getting a "Received a NAK to the SET_CONFIG command from modem" error whilst trying to run Pi-star with different input and output frequencies. Here's what I have learned: 1. The problem occurs in the YSF mode. Don't know about other modes. I have Self=0 and RemoteGateway=1....

Re: Display corruption?

The download was provided as a community service so that people would NOT have to: 1. Install the software to build C and C++ programs. 2. Install the necessary libraries. 3. Obtain the source code off of Github 4. Build the code. 5. Test it. (I actually test things I do.) The point is *ALL* the inf...

Re: Display corruption?

You need to set OLED type to 3 for the 0.96" and 6 for the 1.3". You won't see the driver problem if you have a 0.96" display with the SSD1306 controller. Believe me, I played around with ALL the settings a lot before I downloaded the tools to build the library from source code! BTW, the driver info...

Re: Display corruption? [solved]

This has been bugging me. The 1.3 screen works fine, the 0.96 does not. Here's what's going on. The 1.3" screen uses the SSD1306 controller. Adafruit uses this controller on all their OLED screens. The (cheap) Chineese OLED screens use an older SSD1106 controller. Raspberry Pi uses the Adafruit OLED...

Cannot (Permanently) disable APRS

It seems like Pi-star really, really wants APRS data reported..... Through the expert menus for MMDVM and YSF I set APRS Enabled to 0. Following updates or reboots it gets turned back on. I've edited the .ini files in /etc. Same result. The only way I have found to really kill it is to redirect the ...

Re: Using Hotspots in close proximity to one another

The receivers are total garbage. They also make great mixers. I solve most of my problems by placing a 6-10 dB attenuator between the hotspot and the antenna. You can find SMA attenuators that will work well. The DV4mini placed a 6 dB attenuator on the PCB, which is the right thing to do. I have yet...
