jeremushka,
Thanks.
I updated the project description and added arduino sources. The pins I1 and A are used for power supply, and I2 for the datas.

thank you for this additional information.

Hello,

Is-it possible to sleep the NRF24L01 module without sleep the arduino by the sleep(xxx) function ?
In my case, i would like limited the consumption of my circuit but i need to use the arduino in order to read the serial interface.

Regards.
Tristan

thank you for this additional information.

@Yveaux, I tried with an laboratoy power supply with the RMF95w and NRF24L01, and the same code.

Test with RMF95w :

• laboratery power supply : OK
• 130mW power supply : KO

Test with NRF24L01+ :

• laboratery power supply : OK
• 130mW power supply : OK

The consumption is the same in the two tests : 38mA max, 10mA mean, 4mA min.
In fact I would like to understand why the arduino restarts, is there a watchdog in the Mysensors library to monitor the supply voltage?

PS : I also tried with a larger capacitor without success.

@Yveaux. good idea, yes the power supply is a bit special. It's une AC power 6v limited at 130mW. I used a Graetz rectifier and LDO 3,3v regulator. In fact, i have a similar project with NRF24L01 without issue. I think rfm95w consumes more energy than nrf241L01.

For you, what is the best way to solve my problem ? Perhaps a super capacitor ?

Hello,
I implemented a node with Arduino pro mini 3.3v with a RFM95w module. I used Mysensors PASSIVE node exemple.

My problem is i have an infinite loop/reboot in my serial log. Do you have an idea why i'm having this issue ?

Hello,

I'm looking for an implementation of gateway based with esp8266 with a possibility to change SSID/password by web page and not static configuration as mysensors examples.
What is your solution ?

I'm trying wifimanager library but i have some difficulties about MY_WIFI_SSID and MY_WIFI_PASSWORD used by Mysensors but not wifimanager. Is it possible to use wifimanager with mysensors ?

Tristan

I created an 1.0.4 version without warning compilation. I removed "i" and "len" unnecessary variables.

@Secator,
I use an Arduino pro mini 3.3 V in order to voltage compatible with the NRF24L01

jeremushka,
Thanks.
