DMR working only in RX and not in TX

[IU3NNX]

Hi, i am some problem with my pi-star hotspost, i have setted up YSF and DMR properly, YSF works just great but i am having some difficults with DMR, i can recive data if i set a static TG, for example if i set TG91 i can hear all the conversations but cannot transmit, i have tried with blank codeplug too, i dont know what to do, if i transmit with my TYT md390 i cannot even see nothing displayed in the log, but if i key up with my yaesu ft1xd i can see the logs!

Thank you for your help

Hello,

best wishes for 2021.

Check "§life log", when you transmit.

Same TRX for YSF and DMR? DMR is very sensitive concerning difference between tx-frequency of trx and rx-frequency of hot-spot.

wrong DMR ID?
could annother dmr receiver decode your dmr signal from the origin trx?

So, you have to investigate, if the problem is hot spot related or trx related.

Thank you for your kind help unfurtunatly i have not another dmr radio, i have checked configuration of radio and raspberry, DMR ID seems ok, i have also set the node public, i have performed your detailed procedure here: http://www.kh7ms.com/mmdvm/ and i was able to find right offset for yaesu ft1 but nothing was displayed with any frequency in DMR mode. i am now thinking if it is a problem of the radio, i send you a screenshot of configuration

if you need i can send CPS file configuration.

Thank you very much for your help and happy new year from IU3NNX

The channel window looks identical to my MD390. Only differences I see are that I have:

Scan List NONE (you can't really scan when using a hotspot*)
Admit Criteria COLOR CODE
Allow Talkaround X (not sure why, it really just means the operator can toggle from repeater offset to simplex if persons are in direct range)

{And, of course, different channel name, contact, and group list names}

* having contacts in the group list does offer the potential that, say, a static talk group coming active will be heard even if one is on a different/dynamic talk group -- though Brandmeister tends to lock out other groups for some ugly amount of time.

Thank you everyone for the help you are giving to me, when i go to live log Page i cant see nothing when PTT Is pressed, i checked with an analog radio and i can hear digital sounds from the tyt, i checked talkaround box and i have done a new codeplug but nothing changed.
I noticed that when i try to connect to a local repeater if i press PTT and i reach the repeater i can see a picture of a phone and I can't see this image if i don't reach the repeater. In simplex mode i can see the picture in all frequency, i don't know if it is normal. Sounds weird that YSF works great and DMR don't. i also checked lot of youtube videos but nothing changed unfortunately and nobody seems to have my same problem

On mine for simplex use, I had it set to Repeater Slot 1 on the radio, not 2...?
Give that a try... other than that, as others have said, it kind of all looks ok?

Edit to add:
...TG91... that's Brandmeister, right? If so, have you set a password on the brandmeister.network page and entered that on the Pi setup?
follow this link for more info: viewtopic.php?f=5&t=3167

I have tried TS1 too, and it still doesnt works in TX, i can only RX. The password is correct because i use the same for YSF2DMR and it works great

[IU3NNX]

Yeah, something is weird with that radio, check the DMR ID again and make sure it matches what is in your hotspot also try the hotspot on public.

Yeah, if the password was incorrect you wouldn't be able to connect to the BM server at all and you wouldn't be able to listen to TG 91.

What firmware is the radio (ht) on? Also what firmware is the hat on?

I have re checked and the DMR ID is the same, i can also see the hotspot in my brandmeister page.
The HAT firmware is "HS_Hat:v1.4.6" it is STM32 HAT, i am running a raspberry pi 3b with pistar version 4.1.3.
The firmware of my HT is MD380Tools Ver. 2018-04-01 CP Ver: V01.40

Thank you very much for your help
