[SOLVED] Stuck at I_FIND_PARENT_REQUEST presentation

[nono8223]

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 ?

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.

@nono8223 I've this same problem... stock for days. I tried powering the radio directly with a 3.3volts regulator and capciator between GND and 3.3V pin of the nrf24 but still no luck.

I don't want to duplicate posts but the details of my issue can by found here

Please someone help me...
