does someone know how to certificate a BLE application?

[wen]

I've writen a BLE program for a company,they reqire me to certificate the circuit and the program through a Fixed frequency program,what is the hell?Where to get it?

You can set the frequency by first configuring ble parameters, especially channel map

typedef struct
{
  uint16_t conn_handle;                   /**< Connection Handle (only applicable for get) */
  uint8_t ch_map[5];                      /**< Channel Map (37-bit). */
} ble_gap_opt_ch_map_t;

Please take a look here for details.

There is also Direct Test Mode (DTM) profile but I have never tried it. If you have question on fixed frequency, I suggest reading this page: large.stanford.edu/.../ on Frequency Hopping

I would recommend using the DTM example from the SDK for Bluetooth RF-PHY tests. For more details see the API reference.
