Eddystone TLM secCount always starts with 0

[yuecelm]

normally the secCount in Eddystone TLM should be the time since power-on or reboot:

https://github.com/google/eddystone/blob/master/eddystone-tlm/tlm-plain.md

but the current implementation looks like this in components/ble/ble_services/eddystone/es_security.c

    m_security_slot[slot_no].timing.time_counter = APP_CONFIG_TIMING_INIT_VALUE;

so while generating EID secCount will be always set to APP_CONFIG_TIMING_INIT_VALUE, which is in my case 0.

Is there an explanation for this non-standard behaviour?

Hi,

I need some help to better understand what is the issue, so that I can verify and file a bug report.

From what I can tell, time_counter is correctly updated through the function es_security_update_time() whenever a beacon packet is sent (see the callback function adv_evt_handler() in nrf_ble_es.c.)

time_counter is set to APP_CONFIG_TIMING_INIT_VALUE on Eddystone module initialization, and/or when an EID slot is configured. Is this the issue, that it should have been set to a non-zero value (or not set at all) in any of those situations?

Regards,

sorry the bug report is invalid, my beacon is going to shutdown and a wakeup from it works like a reset. So the 0 value is coming from es_tlm_init which is completely valid...
