40% packet loss from emonGLCDs

Submitted by DaveLloyd on Thu, 12/12/2013 - 15:09

I have a system with 3 emonTX V2s, and 2 emonGLCDs (1 x V1.2 + 1 x V1.3). I use a Raspberry pi to log data. While developing my logging programs I noticed that I was missing a lot of transmissions from the emonGLCDs while reception from the emonTX's is very reliable. I added some code to my logging software to count the number of packets I miss from each sensor (I expect to receive an update every 10 seconds) and email me a summary every day.

I consistently record about 40% packet loss for my emonGLCDs but less than 1% for my emonTXs. Has anyone seen a similar issue?

1 emonGLCD is much closer to the pi than the emonTXs and I tried a different pi in a different location and saw similar failure rates so I don't think range is a factor.

 

Thanks

 

Dave
