On Raspberry PI Zero W (Buster) stop transmitting after less than a second

[algorni]

Just running on raspi pi zero w, connected in ssh over wifi.

pi@raspi-zero-w:~/radio/rpitx $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

I am running exactly the same setup using the latest raspberry pi os lite and it works fine here

[algorni]

BTW i've similar issue also on PI 3 not exactly the same... but similar.... some time transmit some other no,

Same here, on Pi3 with buster, it seems to take at least 2 tries to get something to transmit. Then for 10 or 20 attempts stable, then 1 fails. It seems to work more often than not, but there is a random failure to the scenario.

Same on RPi Zero, clean install of 2020-05-27-raspios-buster-armhf.img. After random time the transmitting breaks. I tested on ./easytest.sh NFM. UPD. I reproduced this issue also on RPi 3b+. It seems that on RPi 3b+ transmitting is break much faster than on RPi Zero.

I did the same as you, testing on Pi ZeroW, it crashed or hung my Pi. I had to pull the power to reset. It was a clean build with latest Raspberry Pi OS image as you noted above. I did get it to work randomly on a Pi 3 model B, but if will fail in less than 1 seconds maybe 10 times before it works once. Same clean latest Raspberry Pi OS build as noted above.

More testing, this time on Stretch rather than Buster... the quick fail happens on Stretch as well, just not as often as on Buster. Using a Pi Zero W, it does not lock up or crash like it does using Buster.

On my RPi3 same problem. Only SSB mod transmits for around 60 seconds rest all mods stops after 3 to 4 seconds. Is there any workaround to address this issue? gpu setting already set as 250 in config.txt.

Unfortunately, I have only have one Pi3 that seems to work, and only with Stretch. At one time I had 4 different Pi devices working with RPiTx, various models. But They were all running Jessie. As I have moved to Stretch and then Buster, various issues have appeared such that my Pizeros and even Pi2s don't work with RPiTx on any recent Pi OS. I have not yet had a chance to test on Jessie again. I suspect this may not be core OS related, but that some library or such has been updated that is breaking RPiTx not the OS its self. I got RPiTx to work in buster briefly, somewhat randomly, but as I updated the same image, RPiTx started to randomly fail more often.

I had the same problem. Try running in the background. &

I have the same thing, it runs but it transmits for less than a second, does anyone has a fix?

[Ghaz75]

What I have noticed is it is having problem on all raspberry pi modules running raspbian buster. Only one OS in which it worked flawlessly is Raspbian Jessie.

I use Raspberry pi zero w, Rasbian buster aka Debian 9. Console - JuiceSSH. The following command works for me:

pifmrds -freq 91.2 -audio /home/pi/Music/v* -ps FBK -rt FBK &

Where pifmrds is alias or path to executive file.

I am trying to use sendiq, which fails.

Same problem here with Zero W and latest raspian.

Same problem here with freshly installed Raspberry Pi OS Lite (32 bit), Debian Bookworm 2024-03-15. Hardware: Raspberry PI 3 Model B v1.2

-- update:

After doing a fresh install with Raspberry Pi OS (Legacy, 32 bit), Debian Bullseye 2024-03-12 it works without an issue.
