@sundberg84 Really nice work.

@sundberg84 yes it gives an ID of 1, but somehow sensor keeps asking four more times. At the end of the cycle, no ID is set. So no sensor shown.

I have a question about using this board as a gateway. Pinout of Mini Pro and Nano are almost identical. I built an adapter board to plug in a Nano into this board. Pin by pin control shows it is OK. I checked connectivity with MYSController. The gateway boots up. When I turn on my battery powered sensor, it asks for ID, the gateway "supposedly" sends it. I watch this from the messages. The sensor does not register. It asks four more times, the gateway responds four times. But sensor could not be ID'd and of course registered.

I am thinking either reception problem on sensor side, or transmission problem on gateway side? Could it be a power problem related with design of the board? Is there any way to identify?

Thanks

@sundberg84 Assembled my second node. This time 5V regulated. One remark and a quick question. You have LE33 in BOM as regulator. I did not have one readily available but an LM1117 which is a totally different package. I had to go through all datasheets to get correct pinout. Could you put labels near pins like 5 3 G?

And the question; dumb as it may sound, do we place a jumper at REG pins when using the regulator version?

@barduino yes I know the boards are designed by sundberg84. I got my boards manufactured as well. What I meant was nicely done.

As for the cable, you could have got raw voltage from the battery booster pin. I was wondering if for any specific reason you had the cable. I understand not.

Regarding protection against reverse polarity, can't you use a diode? You loose 0.6V but there is ample margin.

@barduino nice board. One question, why do you have the cable? Sorry for my newbie question

@sundberg84 Just received the boards and installed my first node with it. I wanted to test all voltages are correct before hooking up the Arduino and NRF. Noticed that I get battery voltage at NRF and booster voltage on Arduino. Checked the schematic. It the board I received is correct after all. Is this intentional that we do not use booster voltage for NRF?

THanks

@gmccarthy As far as I know, NRF channels above 100 should not have interference from Wifi 2.4 Ghz. I was getting 2-3 meters at best. I changed the channel to 110 and corrected the power supply a little. I am yet to implement cling wrap.

I get 10-15 meters between two standard modules inside an apartment. The apartment is like a faraday cage and sometimes I cannot get wifi on the outer extremes while router is in the middle. I am getting sensor readings from one end to the other now, passing through the area where I have the router. So, I think interference is critical in distance.

@ceech for the solar panel and lipo version, could you let me know what type of battery and panel I shoulld buy? Also, is there a tutorial for usage of that version? I am new in solar panel and cahrging batteries. Thanks

@sundberg84 thanks for clarification. From what @Anticimex wrote, I understand I have to tinker beyond my newbie hat to get Arduino to operate without booster. Thanks again.

@sundberg84 I am ordering the PCB's of Ver.8 today. Again, really nice and helpful work for newbies like me. Just one newbie question, though. I understand that both Arduino and NRF are capable of operating down to about 2V. Why do we need the booster in battery operation. I plan to use only Dallas 18B20. Thanks.
