ESP-IDF 05_ble_adv example, no advertisements seen on IOS devices ?

Postby lakid74 » Fri Oct 07, 2016 10:33 am

Hi I might be doing something wrong here but here it goes..
I can compile and upload the sample just fine.
The logs on my esp32 dev board show the app running and moving thru the
ble states
hci_cmd_send_reset();
hci_cmd_send_ble_set_adv_param();
hci_cmd_send_ble_set_adv_data();
hci_cmd_send_ble_adv_start();
So everything appears to be working, but I cannot see the advertisements appear on any apple device. Has anyone got it working on IOS and if so which BLE explorer app did you use ?
Is there any config required in the app before you compile it ?
Thanks

OK, so that proves it works fine for iOS devices.
The question is, does the code need anything done to it (beyond download, make defaultconfig, make and make flash) to make it work ?

Make sure you have BLE stack enabled in make menuconfig.

Yep BT stack is enable (assuming that is the same as BLE stack) ?
sdkconfig, make flash and console output is pasted below.
Thanks for all of your work igrr on the esp8266 and esp32, you are a legend !

ok so replying to myself, using LightBlue on OS X I can see the ESP-HELLO-BLE string but it seems like it advertises itself once and then stays in hci_cmd_send_ble_adv_start forever. If LightBlue isn't running when the program first executes then the announcement is never seen.
Is that what is expected ? or should it continuously advertise ? I am a BLE noob
