I'm using SDK 15.3 and Mesh 3.20 on a system, that works fine with LPN and nodes with friend-features.
The LPN can initiates (establish) friend connection, request status from a group in order to get a unicast address for one of the member in the group.
Everything worksfine, except for the delay until the LPN is up running with a known unicast-address. Sometimes it is fast and other times it takes way to long time (1-2 seconds) wihich is not acceptable.
Because of that, I'm trying to publish to an address stored from an earlier session and then later on establish a friend connection and request status from a group etc
As far as i understand, it is okay to send (publish) an unacknowledged unsegmented message WTHOUT having an established connection to a friend node ! Correct ?
But when I try this, I get a NRF_ERROR_FORBIDDEN returend from access_model_publish() . originated from
uint32_t net_state_seqnum_alloc(uint32_t * p_seqnum)
{
if (m_net_state.seqnum < m_net_state.seqnum_max_available)
{
...
return NRF_SUCCESS;
}
else
{
seqnum_block_allocate();
return NRF_ERROR_FORBIDDEN;
}
}
update ... Have just tried to resend this message more than once... I seem like it is only the very first time the error NRF_ERROR_FORBIDDEN is returned. Herafter everything works fine.
So the answer above is YES,. it is okay to send without having an established friend connection, as I expected :-)
BUT how do i prevent the NRF_ERROR_FORBIDDEN ? Can I check some kind of status of the mesh ?
