Is there anyway to make the ble nano 2 just advertise in one channel (just advertise in the 37)? I am using the arduino ide, and I can t find any method or variable to set to make this.
I don’t know about the Arduino library, but in the Nordic SDK I saw a SoftDevice API that allows you to set the advertising channels. The API is called sd_ble_gap_adv_start():
There is a channel mask inside the p_adv_params argument to this function.
I have not yet tried the Nordic SDK on the BLE Nanov2 board, but I have compiled one of the examples. My impression is that if you want to do something special, you need to move away from the Arduino library.
