Greetings, I am using an Electron to take readings from a Maxbotix sonar sensor to read the height of a stream every 15 minutes, and then upload that information to data.sparkfun.com . Each reading is identified by number, so I am trying to track this with a retained variable that will survive the d…

I believe this is a known problem in the current version of the electron firmware, 0.4.8, that is fixed in the upcoming version, which should be out soon. [image] Backup Ram Stopped working (Issue with 0.4.9) (updated) Troubleshooting I confirmed that the code below works …

I’m happy to report a success. retained,variable works great for me and my electron system version 4.8-rc.6 I use retained to preserve a daylight savings time flag; otherwise, my electron goes back to sleep for an hour after waking up from deepsleep. I learned a few tricks from your snippet. than…

When my Electron wakes up from Sleep Mode the retained variables are working most of the time. In a 12 hour period with Sleep Mode called every hour after a 1 minute of wakeup and then back to sleep two or three times the retained variables did not hold. Is anyone experiencing this? I am using firmw…

Update: I’m now satisfied retained variables work in 0.5.0. ignore the following: I ran a quick test on my electron and it certainly looks like the retained variables aren’t retained anymore with 0.5.0

Thanks @Erhughes1944 for checking.

On testing a little more carefully, everything seems to be working. I print a counter after each warm start (recovery from deep sleep) and the counter is incrementing as it should. I use Time.now() to detect a warm start. My retained time should be close to the current time. On cold start the re…

@Erhughes1944 maybe you are experiencing the inconsistency I am. For a majority of times values are held. For example like I indicated earlier in a 12 hour period they hold for 10 out of the 12 sleep cycles. See if you can do more testing over a period of time. Why did you think earlier they were no…

Based on your post, I started my test Electron at 0130 and just checked at 0630. It ran 210 deep sleep cycles. Unfortunately WIN 10 loses the serial connection so the log just has the start and end. However, the count is about what I expect and it did do 210 consecutive cycles of run 30 seconds …

Thanks @Erhughes1944 . I will continue monitoring on my end. So far today the retained variables are holding their state.

Any news on this issue? I am having the same problem…
