Hi. I'm considering to develop the product with DA14585.

First, the topology of my project is that DA14585 is going to be Peripheral side as sensor product, and Smartphone will be Central role.

I just want to get a sensing data from Peripheral as serial data communication.

And I'd like to use AT-Command as "CodeLess" with external MCU on my sensor product in order to make the development easy.

My plan is like an attached image.

In that case, can I develop the sensor product using CodeLess SDK?

HI dialog

固件国标p on GLOBAL_INT_START

how to find stop reason??

i change connection interval as below , Is connection interval effect my Firmware??

static const struct connection_param_configuration user_connection_param_conf = {
/// Connection interval minimum measured in ble double slots (1.25ms)
/// use the macro MS_TO_DOUBLESLOTS to convert from milliseconds (ms) to double slots
.intv_min = MS_TO_DOUBLESLOTS(50),

DA14585密码配对问题

HI：

您好。

我的需求是：连接da14585必须进行密码配对后，才能读写GATT服务。现在遇到如下问题：

我开启了DA14585密码配对的功能。我使用nrf connect 这个apk去连接DA14585,会弹出框让你输入密码。但是，我点击弹框的“取消按钮”，我仍然可以操作GATT服务。我不知道这个问题出现在哪里。

如果您方便可以电话联系：15323897245.感谢！

Multiple DSPS_Device connecting to single DSPS_Host

Hello,

I am trying to have multiple DA14585 chips running the DSPS-Device software connect to a single DA14585 running the DSPS-Host software. In theda1458x_config_basic.hfile, I increased the#define CFG_MAX_CONNECTIONSto 2, but still only one of my devices connected. Do changes need to be made elsewhere or on the device software side?

Thanks,

Ansel

DA14585 rssi convert to dbm

hi dialog

i have made a distance test ,use da14585 and one beacon. It seems that the API provided by the SDK does not match the reality。

i use

uint8_t ble_rf_rssi_convert(uint8_t rssi_reg) { // NOTE: Approximate conversion corresponding to the following formula: // dBm = (0.474f * rssi) - 112.4f. return ((rssi_reg >> 1U) - 112U); }

I put the test results in the following pdf，Please pay attention to the form。thank you very much

Synchronizing time with DA14585

Hello,

I have an application where a DA14585 is connected to an I2C ADC and sends measurement data via bluetooth to a receiver connected to a computer. I would like to synchronize the time on the computer with the sensor board. This way, I can send time stamped data from the sensor board and not have to worry about time skew during transmission or data processing. The receiver would simply subtract the synchronized time from the data's time stamp to calculate when the sensor measured the data.
