Hi,
I have a setup with 3 nodes (A, B and C). Nodes B and C are running the standard OTA 802 example (WaspOTA_802_1.pde), and Node A is running the same code but modified to send sensor frames as from the standard waspmote start program (wasp_start_program-full_802_v1.pde).
If I run Node A on its own, I can collect the sensor frames from it and scan the node (using the OTAP scan_nodes command in BROADCAST mode). Everything is fine.
If I now turn on Nodes B and C, I am still able to collect the sensor frames from Node A. However, if I run the OTAP scan_nodes command in BROADCAST mode, am I only ever able to see Node A. never Node B and/or Node C. I can however reset each node individually using the OTAP reset command.
If I turn on all three nodes and perform the OTAP scan_nodes command in BROADCAST mode, then I am initially able to see all three nodes, but never again there after.
If I switch off Node A after the problem occurs, I still cannot see Nodes B and C until i reset them.
If only Nodes B and C are on, then scan_nodes always performs as expected...i.e. it works ;)
The code on the Nodes was compiled using Waspmote IDE v0.2 (API v22.0) under Linux.
The code running on Node A is as follows:
Code:
// XBee packet forming variables
packetXBee* paq_sent;
int8_t state=0;
long previous=0;
char aux[200];
char* macHigh=" ";
