How to pair/connect with a MAC address

Hi. I didn't specifically raise another ticket. There was a discussion going on a parallel issue and I mentioned that I wanted to try connecting with a MAC address instead and I was waiting for an answer.

Sorting that has enabled me to move on to the next problem.

You can close this thread.

Seems like you got the assistance you needed from my colleague Vidar in your other ticket: Can connect to uart_peripheral by UUID, but can't connect to a non-Zephyr product

In the future, try to keep to one ticket per subject, or let us know if you have multiple, so we can confer/discuss internally to avoid any miscommunication.

Let me know if you have any further questions here or if this case can be closed.

Best regards,

Simon

Hi,

Thanks for that, but it's not answering my question in terms of the syntax for the mac address. I guess this:

target_mac_addr

is where the mac address itself is stored, but what type of variable is this?

So , for example is it a string of hie kind of format:

45:67:A5:76:AA:FF

Or just a hex number such as

4567A576AAFF

Or...?

Thanks!

Try something like this (assuming there are no conflicting filters already set in your project:

Set up a filter for the MAC address you're interested in connecting to:

err_code = nrf_ble_scan_copy_addr_to_sd_gap_addr(&m_mac_filter, target_mac_addr);
err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, &m_mac_filter);
m_mac_filter.addr_type = BLE_GAP_ADDR_TYPE_RANDOM_STATIC;

Enable the address filter:

err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_ADDR_FILTER, false);
APP_ERROR_CHECK(err_code);

Setting up and enabling a filter should be done before you start scanning.
