Advertising Configuration

[Nguyen Trong Tuan]

Hello,

I have some questions relate to Advertising:and RF ANT:

1. As I understand about advertising, there are only 3 channels, which can broadcast the advertising, are 37, 38, 39. Now I want to broadcast in 1 channel only. So How can I configure this?
2. I want to broadcast advertising via ANT. So I wonder if the GPIO number 24 (ANT) is the Bluetooth signal or something else??

I hope to see the answer as soon as possible. Tks.

Best regards,

[Kenneth]

Hi,

1. This is configurable when calling sd_ble_gap_adv_set_configure, see channel mask in ble_gap_adv_params_t:

2. Please follow the PCB guidelines and reference layout closely, the 2.4GHz antenna with tuning components are placed after the ANT matching network yes (typically labeled 'RF' in the reference circuitry schematics).

Best regards,

Hi Kenneth,

1. Thanks for your reference but Can I explain me how Can I choose specific channel (37, 38, 39( to broadcast the advertising?

2. Can you show me example that show me how to receive or transmit the Advertising?? Sr for this question but I really don't understand clearly about ANT in this board. If you can give me some docs to read about this area, I'm very appreciate.

Thanks,

Best Regards,
