NRF24L01 can't find parent on gateway

[alfredb]

Hi there,

I'm using an ethernet gateway on an UNO R3 with some locally attached sensors and an NRF24L01 attached to it. The locally attached sensors work fine (sending to Domoticz).

Now I have another Robotdyn UNO with one sensor attached and an NRF24L01 but I can't get it to find the parent on the gateway.

Tried lowering the power and moving the two closer and further away from each other, but all makes no difference. The node id get's assigned. Below are the logs from both gateway and client:

@alfredb Please upload your GW & node sketch. Are you using nRF24L01 or nRF24L01+ radios?

@alfredb
Hi there, meanwhile I've been testing with another gateway (on a NodeMCU) and this worked right away. So there is an issue here with the NRF24L01 module on the Uno, perhaps it has something to do with using the ICSP connections for the NRF24L01 module or the combination with a W5500?

Regards

[Oitzu]

Short: probably. TrY soft spi for the nrf24

[tekka]

@alfredb nRF24L01 (non-P) are not supported in 2.0.0, these radios have limited data rates (only 1 and 2Mbps, no 250kbps). I assume you used a different module on your NodeMCU GW?
The good news is, I've added a fix to 2.0.1 (dev) to support non-P modules, you try the dev lib and set

#define MY_RF24_DATARATE RF24_1MBPS

on all nodes an GW.

[alfredb]

@tekka Thanks again, I'll give it a try! I already defined the limited data rate but I was not aware of the fact that the non-P type was not supported.
