Universal wireless sensor board w/NRF24l01+ and ESP8266 socket - ceech board

[ceech]

I'm sorry to hear that. Is there something I can do?
The LEDs have solder jumpers next to them. The top one has one to the left, and the bottom one has one to the right. Just pour solder so that both parts of the jumper get connected.
The white connector is Japan Solderless Terminal or JST. I believe it is a XH series with 0.1 inch spacing. The way I connect the wire is I bend the longer ears with pliers over the isolated wire and use solder iron to solder the shorter ears to the stripped wire.

I see the LEDs and understand now. I had got some loose in the shipping packet and thought I had to solder them onto the board.

[ceech]

They are extra. Enjoy.

EDITED

Nevermind!!

"- with CE and CSN pins connected to digital pins 7 and 8 (you must update MyConfig.h with these values). There is a 4.7uF capacitor connected across Vin and GND of the port"

[AWI]

@shabba You do not need to update MyConfig.h. Just instantiate MySensor with the right parameters (default is 9, 10).

// PIN Radio
#define RADIO_CE_PIN    7       // radio chip enable
#define RADIO_SS_PIN    8      // CS SS serial select

...

MySensor gw(RADIO_CE_PIN, RADIO_SS_PIN);

Hello,

I'm trying mine... any idea why the gateway doesn't receive it at 20cm distance ?

@ceech sorry seems the radio was dead ...

[epierre]

@ceech I have an issue on a board (lipo+solar) where when I put the programmer it works, when I remove it and leave it on battery it doesn't... battery is 94%, I checked sensors get the energy.. but no more radio it seems, an idea ?

[ceech]

@epierre It is probably a loose contact on the battery connector. Try using a multimeter and check the important connections.

[epierre]

@ceech can you point me to the wirings ? thanks,

[ceech]

@epierre Which board are you using?

[epierre]

on this one this is the lipo+solar.

On the other thread, I mistakenly ordered the "standard" version through mysensor website, and had no time till now to test this out... so bard both weren't proposed...

[ceech]

@epierre The battery is connected with the marked trace:

It goes to the switch an over to the voltage regulator:

You should measure battery voltage along those lines with respect to the GND. On the other side of the voltage regulator there should be 3V3.

On the side note -- you can use those boards that you've mentioned on the other thread to charge the battery. No problem.

thanks, but I should not have mixed both, my issue is with the other one.

[ceech]

@epierre The one with LTC4067 or the one with LTC4079? It's probably the one with LTC4067.
Here, this is the battery path to the charger:

and then to the voltage regulator:

[epierre]

on the LCT4067, I have 4.17 , on the battery, VCC/GND gives 1.608, same on programmer pin. But this is correct with the programmer, so I get I have an issue from the battery circuit voltage transformation.

on the standard one LTC4079, voltages are correct, 4.17 on Vin/GND, 3.3 on VCC/GND

[ceech]

@epierre It's either the LTC4067, or the voltage regulator. Can you send me the board back?
I'll repair it and send you back.

[epierre]

I'll repair it and send you back.

hello fine, also I wanted to try the thermopile so there will be more on return ;-)

In the meanwhile, how can I have my solar panel on the LTC4079 ? can the lithium charger do the trick ?

Thanks,

[ceech]

@epierre I've received the board and repaired it. I had to replace the battery management IC. The LTC4067. The output was fried. I also replaced the voltage regulator while I was at it.

@ceech thanks a lot, any idea why this would happen ?

what kind of bluetooth module are you using ? I've managed nothing good with the HC-05, maybe faulty hard to know.
