So because of your document, I was able to implement the DMR to YSF interconnect. The explanation helped me very much. I did, however, had to mkdir another completely separate directory and copy the contents of MMDVM_Bridge into it, because I figured the instance already running ASL<-->Echolink<---->DMR might get affected, as the DVSwitch ini needs modification to reflect the fact that I am.

The MMDVM firmware site link you gave, looks to be the source code to compile the firmware and a whole order of magnitude more complexity again if we had to compile it then only to find it isn't compatible with the MMDVM boards we have and that assumes we find out how to install the updated firmware onto the MMDVM board The RB_STM32_DVM is yet another Multi-Mode Digital Voice Modem that gives new life to analog repeaters by allowing them to become digital capable. The STM32 has an on-board microcomputer, so there is no need for a separate Arduino or other processor board. This board, plus a platform running MMDVMHost is all that is required

New functions, modifications and improvements of BrandMeister appear sometimes at such speed it is difficult to keep up I ended up with a dual hat module that plugs onto a raspberry pi - and after 2 months of being frustrated and thinking it was broken, i found my issue - it's not an HS_Dual_hat at all it's an STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO). The documentation on this fact is pretty sparse, or I've just missed it a LOT .md' on Andys page at GitHub for the MMDVM v1.5.2 firmware I chose not to complete the HAT flash proceedure.

DVSwitch Mobile will certainly contribute to your leaning and exploration of digital voice modes used in amateur radio. 73 de Joe W8RIK Table of Content This lack of documentation, no test points on the mmdvm boards, nor oscilloscope trace examples of proper operation makes troubleshooting a blind endeavor. This is NOT the way to work for the easily frustrated or weak of heart !!! The parrot function on YSF and DMR still both work lousy.

Problem with MMDVM_Bridge DMR/NXDN ID lookup thread. Bj DV8AWC. 6/25/20 #6820. Hello, i have noticed that the MMDVM_Bridge DMR/NXDN ID lookup thread is returning an incorrect content for DMRIds.dat and NXDN.csv. Lookup thread is working as usual. Maybe some changes on the DMR/NXDN ID's db server path While a complete appliance, it came with minimal instructions needed to make it operational (but in all fairness, your are pointed to the necessary documentation on the web.) Given that this is using a standard Raspberry pi - zero board with the MMDVM expansion option leveraging the Open Pi-Star software - it is a rather generic package Now follow the DVSwitch Android instruction at the bottom of this doc.

What you configure here will appear in your BM Dashboard at brandmeister.network. A note about DMR-IDs: You do NOT need to register for a new DMR-ID for this hotspot I have been making a repeater with mmdvm and initially used this same board. I had a lot of problems with the sound quality (tremolo & pixelations) I was receiving from the network. Since I was working with a repeater that had no documentation on how to connect the mmdvm, I decided to change the board to one I already knew, to rule out issues.
MMDVM HotSpot for RPi - type B The main goal of this project was to design a HS board, that could easily be assembled using just normal tools as found in an average equipped amateur electronic workshop. All resistors, capacitors, coils and LEDs used in this project are of the size SMD 0805 or bigger. This should make the assembly of the board much more frendly to a homebuilder who only has. Good quality MMDVM hot spot kit. This is a good quality hot spot hat that is compatible with Raspberry Pi modules, especially the Pi 0W which fits inside the included metal shell. The kit requires some soldering to attach header pins to your separately purchased Pi 0W
Often, saved parameters in the MMDVM are loose, so if you set the port. when you reboot the modem, it change itself. As you say, to work at 115200, you need install NextionDriver, written from ON7LDS. There is a document on how to set the parmeters. Be careful, the actual rel should be 1.02 (shoul be) Cia This section contains documentation with technical information about the Raspberry Pi hardware, including official add-ons and the Pi itself
