ble_app_rscs exemple : connection impossible

[QuentinD]

Hello

I would like to use the extended advertinsing packets from Blutooth V5 as used in the "ble_app_rscs" example.

My problem is that I can't connect via the extended advertinsing packets.

If I use the "ble_app_rscs" example and try to connect via nRF Connect, I receive a "Error (0x85) : GATT ERROR" after the connection attempt.
But if I use the "legacy advertising" (by removing the following lines in "advertising_init"), I can connect to it:

init.config.ble_adv_primary_phy      = BLE_GAP_PHY_1MBPS;
init.config.ble_adv_secondary_phy    = BLE_GAP_PHY_2MBPS;
init.config.ble_adv_extended_enabled = true;


My smartphone is a Samsung S10 (version android 10)
I develop on the PCA10056 board (I use the RC clock source)

Unfortunately I don't have sniffer... So, could you try on your side to confirm if the problem comes from the code or the Smartphone?

Hi Quentin, 

I'm seeing the same result here on my S10. Most likely it's the phone limitation. I will try to test on other phone. But most likely it's the phone issue. The ble_app_rscs_c can connect with no problem with the ble_app_rscs.

Hi again Quentin,

We got test result from other phone as well. On Huawei P30 Pro, Pixel 4 they can connect to the device fine, but on Sony Xperia and Galaxy S10 it's not possible to connect. So more likely it's the issue with the phones.

Thank you so much Hung Bui ;-)
