What value is BLE_GATTS_ATTR_LENS_MAX ?

[Roger Clark]

This may be a stupid question, but...

What value is BLE_GATTS_ATTR_LENS_MAX

Its mentioned a lot in the SDK, but I can't actually find a value for it actually defined in the SDK or elsewhere ?

Have a look in the file ble_gatts.h:

/** @defgroup BLE_GATTS_ATTR_LENS_MAX Maximum attribute lengths
 * @{ */
#define BLE_GATTS_FIX_ATTR_LEN_MAX (510)  /**< Maximum length for fixed length Attribute Values. */
#define BLE_GATTS_VAR_ATTR_LEN_MAX (512)  /**< Maximum length for variable length Attribute Values. */
/** @} */

A tip is to use some kind of "Search in all files" functionality in your IDE. In Keil you can press CTRL+SHIFT+F and type in e.g. "BLE_GATTS_ATTR_LENS_MAX". That will lead you to ble_gatts.h.

Thanks.

I'm not using Keil, I'm using NotePad++. I does have a very good multi file search, but I was looking for something like

ifdef BLE_GATTS_ATTR_LENS_MAX

But BLE_GATTS_ATTR_LENS_MAX is not actually the name thats defined, - from what you posted the values are BLE_GATTS_FIX_ATTR_LEN_MAX and BLE_GATTS_VAR_ATTR_LEN_MAX

Anyway. Thanks again
