I've been having unusual problems with my brick PowerFlarm for several



flights.







Here's the history of my use of PowerFlarm: It was installed by Rex Mayes



during the winter/spring during my annual inspection. I first flew with it



about two months ago, and have had about ten flights total. About two or



three weeks ago (after May 13) I uploaded the latest firmware for the



PowerFlarm brick and for the Butterfly display. I think, but am not sure,



that the problems described below all occurred after I uploaded the lastest



firmware.







Here's what I've experienced:







(1) It seems to work fine on the ground, and usually initially during the



flight, but periodically during the flight it goes into the following mode:



There's a warning message on the screen saying "Waiting for Flarm." Last



week I was flying in close proximity to three other gliders all struggling



to stay up in the same area, and during a period lasting over an hour my



PowerFlarm failed to work, with the above message constantly on the screen.



Later in the flight it resumed working again. It's been doing this for



several flights.







(2) Periodically the TX square turns from green to red, while the GPS



square remains green.







(3) Once, while in flight, the screen turned to the boot-up sequence I saw



previously when I was uploading software using the USB key. This has not



happened again during the subsequent several flights. (The USB key was not



attached while I was having this or the other problems.)

Anyone else having problems of this sort? If so, I'd love to hear how you



solved them, it you did.

Mitch,



My unit arbitrarily shut down and restarted three times in flight today. Similar of just all the sudden seeing the initialization screen and then restart. Frustrating was that it seems to change my V7 vario setting when it restarts. The log file was good but very odd.



TT

This one sounds like a power issue to me, especially that another unit (V7) seem to be affected the same time. otherwise I cant imagine how it will change settings in unrelated instrument.
