Solved!

I fixed it by connecting the radio directly to the battery without using the DCDC boost I use for powering the Arduino Pro Mini.

Hi,

I currently have a couple of MySensors boards with Arduino Pro Mini + nRF24 radios communicating with a Raspberry Pi Gateway.

Today, I wanted to add a new sensor to my network (moisture level sensor). I placed on my protoboard the Arduino Pro Mini, a DCDC boost, a connector for the 2xAA battery and the nRF24L01+, connected as described here: https://www.mysensors.org/build/connect_radio

When I power my sensor, messages seem to be transmitted to the gateway but the sensor seems stuck at the find parents state (from my understanding). As I already have running sensors, I assume the gateway is working fine.

Here is the logs on the sensor side :

Using https://www.mysensors.org/build/parser, it seems that the gateway received the find_parent request and send its response. The sensor however does not seem to get it.

I tried adding a 4.7uF capacitor on the VCC / GND pins of the radio but nothing changed.

Do you have any idea ?

Hi everyone,

I have a couple of old dev boards with weird microcontrollers (old ARM7TDMI from NXP) lying around.
I would like to use some of them for very basic nodes like door sensor with only presentation message and set value messages.
As porting the complete MySensors library on my MCU does not really make sense, I am looking at the way to build the actual data frames that mysensors is using when passing messages through the radio.
The only informations I was able to find on the website is a description of the serial API but nothing on the actual data that's transmitted through the radio.

Would anyone have any resources or any more details on that ?

Regards,

Personally I would very much be interested in this support as I have an old Due on my shelf sitting there doing nothing. :-)

As the SAM and SAMD are both ARM Cortex-M processors from the same manufacturer, I would assume that enabling MySensors for the Arduino Due should be possible without too much trouble.

Have you had any luck with the nrf24 ? As you said, it's 3.3V like the Due so it should work without too much trouble either.

I have ordered some nrf24 and will receive them in the next few weeks. As I have never used MySensors until now, I'll first be playing around with a bunch of Arduino Nano but then in a few weeks I might try the Due.

Hi everyone,

I've just discovered MySensors a few weeks ago and I find it a very interesting project.
As I like to understand it before trying to setup a MySensors network myself, I have been looking at the code on GitHub.

ARM mbed is a programming environment aimed at enabling easy programming for embedded systems, just like Arduino, but with an approach closer to standard programming (use of actual main function and use of object oriented programming for managing I/O).

My question is : do you think porting MySensors to the ARM mbed platform would be a good idea ?

There are lot of dev boards like the STM32 Nucleo board or the TI TIVA Launchpad that can be programmed using ARM mbed but not with Arduino. As they can all be basically programmed with the same C programs (the device specific functions are managed in the mbed core), porting the project to the mbed platform would enable lots of dev board to be compatible with MySensors at once.
