Bluetooth® low energy helps manage diabetes with insulin pen dosage tracking
我们的SmartBond™DA14531和DA14585 SoC提供了一些独特的功能，非常适合连接的健康产品，如注射器。雷电竞官网登录例如，它们可以从氧化银电池和具有高内阻的超小容量电池操作，确保由于超低泄漏电流和检测第一剂量设置的能力，从休眠到活动模式时检测到第一剂量设置的能力，确保非常长的架子。
These capabilities are to the fore in the “InsulinK” insulin dosage tracker from Dnurse. This Bluetooth LE-enabled clip turns an ordinary insulin pen into a connected pen to capture a log of injections and dose information and provide patient feedback for better and more effective insulin consumption.
Cool solution for cold chain monitoring
聪明的Bond TINY™ DA14531 SoC is the ideal solution for cold chain monitoring. It offers the lowest system cost plus scalable radio power to reduce power consumption to low microwatt levels for extraordinarily long battery lifetimes. Dialog offers various software examples to create, for example, smart labels that beacon their temperature or the lowest-cost direction-finding tags for tracking logistics glows. Ideal applications include vaccine transport and food distribution.

DA14531 connected RSSI levels
张贴了FCharles30分 3回复Dear,
I am running some basic range tests to see if the DA14531 will fit for a project. I am using a DA14531 USB development kit as a BLE connectable advertiser alongside another development kit in the role of a BLE master.
The USB DK is programmed with the version 6.0.14.1114 of Dialog's SDK based on the ble_app_barebone example. Once connected, an app_easy_timer periodically sends a GAPC_GET_INFO_CMD message with the GAPC_GET_RSSI operation. The related handler retrieves the rssi field of the received message and converts from LSB to dBm. From there, I can derive for example minimum, maximum and average RSSI levels observed during the connection with the master.
观察到的水平高于预期，重2到3.当设备彼此4米处时，接收的RSSI平均为-20dBm。如果我用手机或另一个开发套件作为BLE奴隶重现本实验，则平均RSSI级别更接近-50dBm。
The conversion formula I use is derived from the formula in the sdk/platform/core_modules/src/rf_585.c file. Since the DA14531 datasheet specifies a Lres_rssi of 0.5 dB/LSB, I thought the initial formula would give a close enough approximation. Yet, observations would indicate this is not the case, but I cannot find other articles, resources or source code giving any other formula. Am I missing someting ?
Kind regards,
FC

Dear support team,
thank you for the reply. I did not think of investigating source files and was searching through the header files only.
The -127 offset instead of the -112 offset I was using explains partly the abnormal power levels observed.
However, it still seems the RSSI is quite high. Nonetheless, many thanks for your support!

Hi FCharles,
Thanks for coming and posting your question on our new public forum. To get the RSSI, when the device is connected , you should issue GAPC_GET_INFO_CMD with GAPC_GET_CON_RSSI operation in order to request the RSSI values. Since the GAPC_GET_INFO_CMD is sent, you will get a GAPC_CON_RSSI_IND, so you will have to handle this message. The values will be returned to rssi member of the struct gapc_con_rssi_ind. In order to convert RSSI to dBm, please see rf_rssi_convert() in ble_arp.c file. You can also check theSocial Distancing TagsSW示例。
Thanks, PM_Dialog
