LAUNCHXL-CC2640R2: OAD SNP update DeviceInfo characteristcs

Laurent van Poppelen69

Hi,

we have OAD working on Launchxl-cc2640r2 + MSP-EXP432P401/4111 as well as 'Sable-X-R2' + customboard(MSP432P4011). We would like to know if its posssible to update the cc2640r2's DevicwInfoService characteristics values after an firmware upload(OAD) of the MSP432Pxxxx? Thus not having to perform an SNP upload!

regards,

Laurent

Hi Laurent,

I don't understand the question.

Since these characteristics are not writable you can't change the value over the air.

Hi Marie, what we mean is not to be able to update them over the air but from the MSP432Pxxx via the sap/snp master slave connection! So after we update the MSP432Pxxx we could just update the DeviceInfo Service characteristics to match the update release!

Example: FR000.001.003 -> FR000.001.003 (Firmware Release)

rgds,

Laurent

Hello Laurent,

Yes, refer to the SNP_setAttrValue()

http://dev.ti.com/tirex/explore/content/simplelink_cc2640r2_sdk_4_10_00_10/docs/blestack/ble_user_guide/doxygen/ble/html/group___s_n_p___g_a_t_t.html#ga4377f63586f131e5465437dc963c1afc

Although it is mainly intended to indicate firmware inside the BLE module, but perhaps you can use DEVINFO_SOFTWARE_REV to indicate Host version (MSP432) and DEVINFO_FIRMWARE_REV to indicate firmware on the module. Just an idea, not sure what is practiced in real life.
