The objective is to have a device which constantly advertises some status information - this must be always visible to any Central in range.
The device may connect to at most one Central - but must continue to advertise the status information while connected.
So the device has 2 states:
- Not connected; doing Connectable advertising;
- Connected; doing Non-connectable advertising.
The information in the advertising doesn't change rapidly, so I use the Advertising Timeout as the point to update it; On the timeout event:
- Update the advertising data;
- Re-start the advertising.
This works fine for Connectable advertising, but not for Non-connectable.
I have tried the solution here, but it doesn't work:
I suspect the problem is related to the fiddling with priorities.
So I started again from scratch,
I have attached my modified main.c from the SDK 15.3.0 'Template' example.
Also attached is ble_advertising.c, as I've added some extra logging - but no functional changes.
Here is the trace of a connection:
<debug> app: ADV: GAP Conn <info> app: GAP Conn <info> app: Non-connectable, Non-scannable advertising; Handle 0 <debug> nrf_ble_gatt: Peer on connection 0x0 requested a data length of 27 bytes. <debug> nrf_ble_gatt: Updating data length to 27 on connection 0x0. <debug> app: ADV: evt 35 <debug> nrf_ble_gatt: Data length updated to 27 on connection 0x0. <debug> nrf_ble_gatt: max_rx_octets: 27 <debug> nrf_ble_gatt: max_tx_octets: 27 <debug> nrf_ble_gatt: max_rx_time: 328 <debug> nrf_ble_gatt: max_tx_time: 2120 <debug> app: ADV: evt 36 <debug> app: ADV: evt 33 <debug> app: PHY upd req <debug> app: ADV: evt 34 <debug> app: ADV: Conn Parm Upd <debug> app: ADV: Conn Parm Upd <debug> app: ADV: Conn Parm Upd
I get the GAP Connect event, and the Non-connectable advertising starts OK.
But, when the Non-connectable advertising times out:
<info> app: Adv Tmo: Conn Hdl 0000; Adv Hdl 0; Mnf07 <info> app: Non-connectable, Non-scannable advertising; Handle 0 <error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] at main.c:780 PC at: 0x00031387 <error> app: End of error report
I get NRF_ERROR_INVALID_PARAM at this point:
err_code = sd_ble_gap_adv_set_configure(&m_advertising.adv_handle,
&m_advertising.adv_data,
&adv_params);
APP_ERROR_CHECK(err_code);
This is in non_connectable_advertising_start() - it worked fine to initially start the Non-connectable advertising, so why does it fail on re-starting it?
None of the parameters should have changed!
It is an unhelpful Error code as it give no help in identifying which parameter was invalid, nor how it was invalid. And, because it's an SD call, there's no way to step in to see where it's going wrong.
