蓝牙BLE的射频测试DTM测试固件

各位开发者,您们好,


我司使用ESP32研发了无线设备。现在客户要求进行射频测试,并由 DEKRA 提供了Direct Test Mode (DTM) 测试使用的上位机。但由于我没有在官方找到关于 DTM 测试的固件或则参考内容,从而无法继续进行。麻烦了解DTM测试的官方人员或则开发者能够给予帮助。


非常感谢各位,

王旭

How to Perform the Direct Test Mode (DTM) of BLE Test

Hi All,

I was asked to provide the DTM test for my product, but I don't know how to complete this. Do you have the methods and procedures for this test? Can you give it to me?

Thanks,
Best Regards

SPIFFS does wear levelling internally, and expects that it operates on raw SPI flash. As such, it can not be used on top of another flash translation layer, such as wear_levelling library, or on top of encrypted flash.
:D Thx!

How to use WearLevel in spiffs?

Hi there,

SPIFFS supports wear leveling, but I can't using wl_mount() to mount wear level in SPIFFS partition.
So I have two questions:
1. Is the SPIFFS partition already installed with wearlevel?
2.If 1 is not, how to use Wear Level in spiffs?


regards,

Re: 如何格式化FAT文件系统?

这一段 有进行格式化的代码请仔细分析代码。 menuconfig 中先选择 WL_SECTOR_SIZE_512 ,之后选择 CONFIG_WL_SECTOR_MODE 。 非常感谢您的耐心解答! 我最后是使用esp_partition_erase_range()来擦除分区后再esp_vfs_fat_spiflash_mount()上fat分区。 参考:http://bbs.esp32.com/viewtopic.php?f=13&t=8773&sid=ada79d52fe703b8c6587605652ba7c28 因为个人能力问题,在您提示下仅能找到f_mkfs()大概是作为文件格式化部...

The simplest option is to call esp_partition_erase_range function to erase the entire partition. Then initialize WL and FATFS. This will result in the filesystem being formatted.
:D Thx.

可以使用 “安全模式” 去避免这种情况,menuconfig 中配置 CONFIG_WL_SECTOR_MODE
您好,

不知为何,我所使用的IDF的menuconfiguer的该位置并没有该选项,也仅仅是有设置wl大小的选项。请问您知道为什么吗?
