1.6.0 not working at my MMDVM_HS_DUAL #145

Open dl1bz opened 2 years ago

I have a MMDVM_HS_DUAL with 12,880 MHz. With FW 1.5.2 all worked, if I compile the newest 1.6.0 MMDVMHost says NAK from modem. MMDVMCal also not working. Flashing backward to 1.5.2 bring all back, the modem works correct.

ok, here is my solution: a) MMDVMCal don't work I delete in an actual MMDVMCal all serial speeds higher than 115200. That brings me MMDVMCal back to work with the MMDVM_HS_DUAL and 1.6.0. I think we need a command line parameter with defined SerialSpeed in MMDVMCal ?!? You cannot put a defined serial speed if you start MMDVMCal.

b) MMDVMHost don't start I need to set UARTSpeed=115200 in MMDVM.ini With UARTSpeed=460800 MMDVMHost don't start with this MMDVM_HS_DUAL.

For now all is working now. But I think there are a few things need to be fixed with the newer, higher serial speed parameters.

Yes, but the lastest MMDVMCal don't detect the modem anymore. There is no option (at command line) to bring the serial speed down. Only if I modify the source code of MMDVMCal and delete higher serial speeds as 115200 the MMDVMCal come back to work with my MMDVM_HS_DUAL and 1.6.0. Earlier there was not such a problem. That was what I meant with "a few things need to be fixed" :) The FW 1.6.0 itself works now.

Thanks for pointing that out. I’ll try and fix it this evening UK time.

Great Jonathan. If you fix it I will try again. Thanks a lot.

I dislike auto-baud intensely, sorry. I've updated MMDVMCal to take a non-optional speed parameter, which should fix things for people. 115200 for hotspots, and 460800 for modern MMDVM modem versions. It also allows for 230400 baud.

Problems with MMDVMCal belong in the MMDVMCal repo.

@g4klx

I've got a patch solution for MMDVMCal on my repo, but I'm my opinion it is still suboptimal, even though it works correctly in my testing. Personally I think it would be best for MMDVMCal/MMDVMHost to try all valid serial port speeds to "autodetect" a modem, or at least try 115200, 230400, and 460800, since those are the ones you now define in the MMDVM config.h That way all compatibility with older firmware for MMDVM and MMDVM_HS is still maintained.

I checked the 1.6.0 MMDVM_HS source code. the USART1 speed is set to 115200, and the Pi-start also set to 115200. After flash the 1.6.0 to STM32, it turn out works with pi-star 4.1.6, but fail to work with 4.1.5 and 3.4.17. Is there any other reason? how to make it work with 4.1.5 and 3.4.17? Thanks for any help.
