Hello all,
I'm facing the following issue.
I'm sending a
snmp_send_trap_generic (SNMP_GENTRAP_COLDSTART);
For debug proposes I'm sending it periodically(5 seconds).
If I set:
snmp_set_default_trap_version (SNMP_VERSION_1);
it works ok. I receive periodically. My SNMP software identifies it as a cold
start.
If I set:
snmp_set_default_trap_version (SNMP_VERSION_2c);
It sends two Trap messages only with the following information:
Source: 192.168.1.235 Timestamp: 2 seconds
SNMP Version: 2 Trap OID: .1.3.6.1.6.3.1.1.5.1
Community: public
Variable Bindings:
Name: .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime
Value: [TimeTicks] 2 seconds (235)
Name: .1.3.6.1.6.3.1.1.4.1
Value: [OID] .1.3.6.1.6.3.1.1.5.1
After that, my system hangs on freeRTOS
If I pause the debugger it will stop on this line, please have a look at:
https://www.freertos.org/FAQHelp.html
"11. I get stuck on the line that starts for( pxIterator = ( ListItem_t * ) &(
pxList->xListEnd );"
So what could cause this issue by just changing V1 to V2c ?
Am I missing some configuration or handling to use V2c?
