Hello guys,
thank you for your intels ! i recieved the pcb and built it, it works
i changed C1 for a 0.1µF, and removed R12
i kept the resistor bridge for isp comm.
i tried to activate buffer with irq but it's going rogue, gave up with that
i doubt that the inclusion button has any utility, it seems to be just an other reset button
It gives me a little serial gateway wich size is about the same as a "sonoff zigbee dongle plus"
i'll have to make an enclosure for it now
i had my answer on ahtxx issue
Hi,
...figured out that the _address is messed up (i guess by mysensors).
It is impossible, because _address is private variable. The private data members cannot be accessed from outside the class (mysensors can not see it).
Сan you try my original library but with class initialization line
AHTxx aht10(0x38, AHT1x_SENSOR); //sensor address, sensor type
i had my answer on ahtxx issue

thanks eiten,
I arrived at the same conclusion, indeed i replaced _address by _i2cAHTAddress in AHTxx library and it works.
I am completely new to cpp (and arduino) but not to developpement, and what bothers me it's that libraries, like mysensors and ahtxx, for example, could compete on variables. Comming from javascript where global variables are avoided i am realy suprised about that. Is this normal behaviour ? what i don't understand is that _address is a private property of AHTxx class, so it should be encapsulated, how could mysensors overwrite it ?
ok, so i figured out what is going wrong, but i don't know how to solve this

if someone can help from here ...
Hello,
i have a sketch for aht10 wich is working perfectly alone
the library is https://github.com/enjoyneering/AHTxx
// AHT10
// https://github.com/enjoyneering/AHTxx/blob/main/examples/AHT10_Serial/AHT10_Serial.ino
#include <Wire.h>
#include <AHTxx.h>
float ahtTemp; //to store T/RH result
float ahtHumi;
AHTxx aht10(AHTXX_ADDRESS_X38, AHT1x_SENSOR); //sensor address, sensor type
void setup()
{
Serial.begin(115200);
Serial.println("- - - - - setup - - - - -");
Wire.begin();
while (aht10.begin() != true) //for ESP-01 use aht10.begin(0, 2);
{
Serial.println(F("AHT1x not connected or fail to load calibration coefficient")); //(F()) save string to flash & keeps dynamic memory free
delay(5000);
}
Serial.println(F("AHT10 OK"));
}
void loop()
{
Serial.println("getting humidity & temperature");
ahtTemp = aht10.readTemperature(); //read 6-bytes via I2C, takes 80 milliseconds
Serial.print(F("Temperature: "));
Serial.print(ahtTemp);
Serial.println(F(" +-0.3C"));
delay(2000); //measurement with high frequency leads to heating of the sensor, see NOTE
ahtHumi = aht10.readHumidity(); //read another 6-bytes via I2C, takes 80 milliseconds
Serial.print(F("Humidity......: "));
Serial.print(ahtHumi);
Serial.println(F(" +-2%"));
delay(10000);
}
but when i try to incorporate it in a mysensor sketch, it stays stuck at aht10.begin()

send(msgHum.set(ahtHumi, 1));
// Sleep for a while to save energy
sleep(UPDATE_INTERVAL);
}
has you see concerning the ath10 code it is exactly the same
both are running with the same arduino nanos
i triple checked my wirering
and a same breakout board is working alone but not with mysensors code included
any idea ?
thanks

hello @monte
thanks for your feedbacks

You don't need resistors to drop voltage on data pins for NRF24, they are 5V tolerant
for generic nrf24+ module yes i know
but that's not what the e01-ml01sp4 datasheet is saying, so i prefer to be prudent, it can't do any arm ("ça mange pas de pain" in french)
Also you don't need SO much capacitance
4,7uF is enough for stable work, as per my experience. Better add second cap 0.1uF in parallel to the big ones.
do you mean 4.7uF for C1 instead of 47uF?
and where would you put the 0.1uF ? on the output of ams1117 or in the input of nrf24 ?
Also, why is AMS1117 connected to ground via resistor?
i can't explain it as i don't fully understand it, i followed this tutorial https://maker.pro/arduino/projects/how-to-use-ams1117
IRQ pin does nothing in current (and probably the last) version of MySensors, so you can skip routing it if it will help you in any way.
ok, good to know, my pcb is already ordered but i'll remember that for my coming nodes.
in current (and probably the last) version of MySensors
may i ask why, what do you mean ?
i'm new here, and as a free software enthusiaste developper discovering home automation since 2 years now (expensive closed zwave, closed zigbee then closed ptvo), i was super glad to finally find a project like mysensors, and on my way to explore it, i progressively understand that it's not as active as it was
hi electrick,
thank you for the hint, i'm so glad that someone finally talks to me
Yes i reached the same conclusion about power supply of the nrf24 board.
3.3V pin from nano can only deliver 50mA when e01-ml01sp4 needs 120mA.
I redesigned my project including a ams1117 between nano's 5V pin and the radio board
https://forum.mysensors.org/topic/12109/nano-e01-ml01sp4-gateway/4?_=1679247873047
next episode when i'll receive the new pcb !
i refactored entirely again my gateway as 3.3V pin from nano is not powerful enough (50mA) for the e01-ml01sp4 (120mA)
nano is rebooting when attempting connexion or serial reading
here is the new schematic and pcb
Hi,
i built a serial gateway with a nano and E01-ML01SP4 nrf24 ebyte module
https://www.ebyte.com/en/product-view-news.aspx?id=114
i posted about it here https://forum.mysensors.org/topic/12109/nano-e01-ml01sp4-gateway
the problème is the gate way is rebooting alone each time i try to read the serial
of course my controler (HA) can't get the data as the gateway is always rebooting
my node (wich is working with an other nrf24 gateway) can't connect neither
my gateway sketch is default one with

some help would be really appreciated
