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

[shabba]

I just want to confirm a few things before I buy :

1. What is needed to programme this? Can it be done via an FTDI board?
2. What bootloader is on it?
3. Besides a sensor and radio (and power) nothing else needs to be added/soldered right?

Thanks!

@shabba

1. Yes, it can. With FTDI or similar board. It is the same process as with Arduino Pro mini.
2. Which is also the bootloader - Arduino Pro or Pro Mini (ATmega328, 8MHz, 3.3V)
3. Nothing else is needed.

[shabba]

Thanks. Ordered a couple.

I'm having a slow day so bear with me :-)

Where do I connect the LEDs? Also what is the name of the white sockets? I want to google procedure for adding wire to the plug part.

Many thanks :)

Warning to others : I blew a radio by connecting a 5V programmer. There seems to be no protection from USB power to the radio.

[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.

[shabba]

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.

[epierre]

@ceech said:

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

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:
