dropped packets

[NLC]

I just rcv'd these from LPL: 3 motes (1 rcv, 2 xmitr, 1 ftdi)
The xmit & rcv motes (RFM69HW, 4Mb flash, mote+ ftdi) are in close proximity (6 in. away). One transmitter pumps a lot of 'ACK...nothing'(s)[see the monitor logs below], the other xmtr seems ok. Looks like quite a lot of dropped packets on this one xmtr. Any suggestions?

You're not using the setHighPower(); setting most likely. Or haven't soldered the antenna.

[NLC]

the other xmtr that came with the same order does not have the same problem. The one in question is consistently spitting 'nothing'. Both do not have antennas soldered in yet but they're in the same proximity to the rcvr (6 in.).

[Felix]

Ok can you show the exact code you're running on the "good" node and the "bad" node.
Have you soldered the antennas?

[NLC]

I'm very new at this, sorry. How do I download the current code on the xmitrs?  I'm using the 1.0.5-r2 utility.

[Felix]

Please take some time and read the page at moteino.com and also my blog www.lowpowerlab.com
And make sure to use the latest 1.0.5 Arduino IDE.
The Moteinos are tested for functionality so there is no concern that they do not work.

Not having an antenna could be the problem. If you aren't able to solder the antenna wire at this time, at least try stripping the end of the antenna wire putting it in the hole, making sure it is has electrical connection.
