@pit said: @pit said: RF24L01 network without SIGNING, OTA feature. My RBoard hangs if it receives a message from gw before reaching the process loop. After some resets it finishes his setup and I get states from my buttons and I can switch my relays in fhem. With small mini, nano sensors and only 2 or 3 values (temp, hum, pressure) there are no problems. Here are 3 logs from my RBoard (id 30) starting sensor (RNNNA-, 2.0.0) Radio init successful send: 30-30-0-0 s=2 c=2 t=3 pt=0 l=0 sg=0 st=ok: Node ready to receive messages... send: 30-30-0-0 s=255 c=3 t=15 pt=0 l=2 sg=0 st=ok: send: 30-30-0-0 s=255 c=0 t=17 pt=0 l=5 sg=0 st=ok:2.0.0 send: 30-30-0-0 s=255 c=3 t=6 pt=1 l=1 sg=0 st=ok:0 read: 0-0-30 s=255 c=3 t=15 pt=0 l=2 sg=0: // ??? // hanging starting sensor (RNNNA-, 2.0.0) Radio init successful send: 30-30-0-0 s=2 c=2 t=3 pt=0 l=0 sg=0 st=ok: Node ready to receive messages... send: 30-30-0-0 s=255 c=3 t=15 pt=0 l=2 sg=0 st=ok: send: 30-30-0-0 s=255 c=0 t=17 pt=0 l=5 sg=0 st=ok:2.0.0 send: 30-30-0-0 s=255 c=3 t=6 pt=1 l=1 sg=0 st=ok:0 send: 30-30-0-0 s=255 c=3 t=11 pt=0 l=13 sg=0 st=ok:Itlead RBoard send: 30-30-0-0 s=255 c=3 t=12 pt=0 l=3 sg=0 st=ok:1.0 send: 30-30-0-0 s=1 c=0 t=1 pt=0 l=0 sg=0 st=ok: send: 30-30-0-0 s=2 c=0 t=4 pt=0 l=0 sg=0 st=ok: send: 30-30-0-0 s=10 c=0 t=3 pt=0 l=8 sg=0 st=ok:Switch 0 send: 30-30-0-0 s=11 c=0 t=3 pt=0 l=8 sg=0 st=ok:Switch 1 send: 30-30-0-0 s=12 c=0 t=3 pt=0 l=8 sg=0 st=ok:Switch 2 send: 30-30-0-0 s=13 c=0 t=3 pt=0 l=8 sg=0 st=ok:Switch 3 send: 30-30-0-0 s=20 c=0 t=3 pt=0 l=7 sg=0 st=ok:Relay 0 send: 30-30-0-0 s=21 c=0 t=3 pt=0 l=7 sg=0 st=ok:Relay 1 send: 30-30-0-0 s=22 c=0 t=3 pt=0 l=7 sg=0 st=ok:Relay 2 send: 30-30-0-0 s=23 c=0 t=3 pt=0 l=7 sg=0 st=ok:Relay 3 Init complete, node id=30 parent=0 distance=1 // ok motion: 1 send: 30-30-0-0 s=1 c=1 t=16 pt=0 l=1 sg=0 st=ok:1 motion: 0 send: 30-30-0-0 s=1 c=1 t=16 pt=0 l=1 sg=0 st=ok:0 send: 30-30-0-0 s=10 c=1 t=2 pt=1 l=1 sg=0 st=ok:1 Now the node works. Could it be a timing problem? Also the received message has type: text. but gw sends 2 bytes in "signerPresentation(_msg)" if I am not wrong. Has anyone an idea? read: 0-0-30 s=10 c=1 t=2 pt=1 l=1 sg=0:1
