Jumbo Hotspot works but keeps closing

Post by WD4IYE »

Hi everyone!

2 months ago I received a Jumbo Hotspot from China that I bought on Ebay. I love troubleshooting but I'm finally ready to ask for some advice. The original hotspot did have a bad MMDVM that the receiver and transmitter didn't work. A new one corrected that issue. The hotspot works fine except it randomly closes every few minutes. I can see activity on the dashboard and the OLED. I haven't made a contact yet because I don't want to be cut off mid QSO. But Parrot works well. Just keeps closing.

Before posting this I have done the following to try to eliminate the Pi-Star closing.

1) Replaced MMDVM
2) Replace Pi Zero WH
3) Replaced 8G with 16G micro SD
4) Created new image for micro SD several times
5) Updated MMDVM several times
6) Used a quality 5V power supply form a Go Pro
7) Used other +2 A 5V power supplies
8) Tried my cellular hotspot to see if it was my wifi
9) Confirmed wifi was not set to sleep
10) Kernel 5.10.17+
11) Platform Pi Zero W Rev 1.1 (512MB)
12) CPU Load 0.64 / 0.61 / 0.57
13) CPU Temp 40.1°C / 104.2°F
14) Live Log

Might be worth running dmesg immediately after the next drop-out (unfortunately, dmesg events are time-stamped in -- I think -- seconds since last boot, so difficult to map to calendar time -- for example:

Code: Select all

[855398.745694] systemd-journald[115]: Received request to rotate journal from PID 1
[855398.764200] systemd-journald[115]: Vacuuming done, freed 0B of archived journals from /run/log/journal/18634e1404184594bc66ddacfba0bf43.
[855399.102491] EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)
pi-star@pi-star-3b(ro):~$
Note the large time-stamp

I always listen to others when I can't figure something out. It does not matter if I don't understand it. As long as its seems like a logic step. I planned on trying both your suggestions but decided to try setting up my Pi-Star config from scratch. Mainly because I had already done your other suggestions several times. I would of tried those again if setting up the Pi-Star config from scratch hadn't of worked. The Pi-Star config I was using was very close to day 1. So I assume something was set wrong or the many updates I did conflicted with by old config. I no longer want to crush my hotspot with a hammer! It was very fun troubleshooting my MMDVM tophat but the closing kicked my butt. I'm very appreciative of your help and hopefully some other newbie can benefit from our post someday.

Thanks again for taking the time to help me.

Ron you could extend the time out time from 240 seconds to 10 min 600 seconds.
Also take all the talk groups off of scan and turn scan off.
Enjoyed our qso and am looking forward to the next.
You might talk to AB4WS Jack Prindle about your problem. I am sure he would be glad to help.
