UART Read Not Clearing Buffer

Thu, 2019-03-21 12:33 -- livingstonem


I am working on a project, using pxp_reporter as a base. I am communicating with an ESP WiFi module over UART.

I have UART configured, and I can communicate with the device. However, after I do a successful ad_uart_read, I always get the same data for any additional read operations afterwards. I do not have this problem when I communicate directly with the ESP device over the USB->UART bridge on the pro development board.

Need to reduce the boot up time for DA14583

Wed, 2019-03-20 12:57 -- karanshah28

Hi Dialog Team,

I am working on a product where we are using DA14583.

We are using DA14583 which gets power up on first time of some button/gpio press. Now the issue is that it takes almost 400ms or more to boot up and start. 

Can we reduce the boot up time below 10-20 ms? 

Basically the competitor products provide such less boot up time. Do we have any controller which can solve our issue? Any options, as we really need to reduce the bootup time.

Hello All,

I am using a BLE peripheral example as a reference for developing my code.

I wanted to add a new Custom service in the same example and refering the documents and the code of BLE peripheral i Created  new files for new custom service with different UUID's and name as  user_cust2_svc.c and user_cust2_svc.h which replicated same  as user_cust1_def.c and user_cust1_def.h .

I was able to build Code sucessfully but when check in BLE scanner i m not able to find my newly created Custom service.

韌體上有設定閒置5分鐘後 藍芽會自動斷線 , 並再擺放約10分鐘後 測試連線是否正常.

下午3點59分28秒 為第一次連線, 並開始斷線15分鐘.

1. 時間3/4 下午4點16分33秒 後連線(第二次). 接著又在下午4點16分37秒 再度連線 (第三次)

da14583 data convert

Mon, 2019-03-04 12:31 -- channing

I have a problem with da14583 iot sensor, I have received 14583 data but I don't know how to convert it to real data. i get data like this bytearray(b'\x02\x02\x03\xf9\xff\x00\x00\x02\x00')
i know the last 6 data are x y z sensor data so x=\xf9\xff y=x00\x00 z=x02\x00 What method can be used to convert to real data? it look like int16 ? thanks

Alter main.c file

Tue, 2019-02-26 03:28 -- Rajapurerohit

Hello all,

I am working on project using SDK 5.0.4 and for my project i need to follow the state machine where, mode of operation switch from one state to another state and that switching of mode/ state i want to keep in while(1) loop along with other BLE activities and check every time the state before move to next state.

Can any one help me, how can i proceed with logic execution as per my requirement and also can change the arch_main.c ?
If i change main file then will it be affect to my entire SDK ?

Urgently need help to proceed further Please.

想問此藍芽裝置是否能夠直接連接我的個人電腦,並且不透過手機或者開發版就能透過藍芽讀取到裡面的raw data,能的話我想請問該如何實施?
還有個人電腦是否能夠同時藍芽連接複數以上的DA14583並且同時接收他們的raw data?
我想透過直接接收到的raw data來做數據紀錄

麻煩你們了 謝謝
