That sounds good, especially if it supported older android as well - could re-use old tablets as controllers

I tried adding ack and that seems to work (see below) yet still the nide does not show up in <resources><nodes> - What am I doing wrong, it all used to work ,,,Argh!

Here is what I get - I think that this shows that the node finds the parent, but then it doesn't respond to any commands from the myc pi. In myc it shows node as down, yet it is 'talking' to the gw so maybe the problem is between gw and controller? But how to test this?

OK I am setting up again with new RF channel and mysensors 2.3.0 version.

So far gw is working a node registers but nothing works after that. I'll keep trying!

@jkandasa
Been very busy recently but a major power outage stopped all nodes data after power restored, so I must look into that and see if it's all trash now or if I can start again. I think at lease one node will need a new bootloader flash, as for the others, who knows?
Never a dull moment around here! - I will of course let you know when I can update on the situation. Internal sensors on the pi are still running fine.

@Tag
Thanks for the info, always appreciated - sorry for delay in reply, been very busy lately.

Just a quick update ....

I have removed the promini and nrf24l01+ from the pi and connected to the laptop. They both work fine and I can see messages from other nodes.

MYC connects serially with the gateway at 38400 (for 3.3v 8MHz module) but still no data.

Connecting a node to the pc and looking at the serail monitor I see it fails to find a parent.....Yet radios, nodes and gateway all appear to be working.

Could it be something simple? I can't think what to try next.

So my old myc went bad (sd card failed) and took with it all my settings and backups (lesson in there).

Now I have new sd card with latest java and myc 1.3.0 and can't get any data from the nodes. All nodes worked prior to this.

Set up is with arduino pro-mini as gateway connected to nrf24l01+ (tried another one and still same results). Internal from mcagent is working fine. But even with auto register and rebooting nodes (in one case even erasing eeprom and reprogramming the node) it still has problems.

The gateway connects to myc and I have tried 'auto' and 'Jserial' etc, all with same results.

Have I missed something? Can I tail the gateway somehow? sudo tail -f /dev/serial0 doesn't produce anything.

Ideas/suggestions welcome!

Just setting up again and tried this - No problem at all! - Thank you!

Just wondering if this works 'both ways' ie controller sends ack for messages received from nodes and waits for ack from node after sending data to node as well?
