关于gpio口的设置
hi there
百忙之中打扰了，请问一下如何将P1_4/SWCLK和P1_5/SW_DIO作为gpio接口使用(比如用来控制led)。
为什么我这样定义不行。就是没有信号输出。
GPIO_ConfigurePin(GPIO_PORT_1, GPIO_PIN_4, OUTPUT, PID_GPIO, false);
GPIO_ConfigurePin(GPIO_PORT_1, GPIO_PIN_5, OUTPUT, PID_GPIO, false);
14580回复APP两条数据，为什么APP只接收到后面一条？

int newDataLen = strlen("$3{\"ret\":0,\"timeSta");
memcpy(bleData, "$3{\"ret\":0,\"timeSta", newDataLen);
bleData[newDataLen] = 0;
attmdb_att_set_value(param->handle, strlen(bleData), (uint8_t*)&(bleData[0]));
prf_server_send_event((prf_env_struct *)&custs1_env, 0, param->handle);
usDelay(50 * 1000);
UART Speed
Hello,
How does changing the pins for the UARTx interface affect the max baud rate? Can I change them as needed? Where can I find the max baud rate of the interface?

Invoking sleep with UART in receive mode
I'm field testing a custom board with a DA14580 and an external MCU managing sensors. When connected (to an Android tablet in my case), the external MCU sends sensor data once per second to the DA14580 via UART. Upon disconnect, I'm invoking extended sleep mode pending a wakeup on a GPIO pin toggled by the external MCU. Functionally, this is working great but we're not seeing the expected low power when we're supposed to be in sleep mode.

No response to AT command in codeless
Hi,
DA14580-01 - Program permanently without EEPROM
Hello,
I was wondering, is there a way to program the device permanently without using an external memory to boot from?
Kind regards
Debug with ST-Link in Keil
We use the PAN1740 containing a DA14580 in our custom board. We pull out the SWDIO and SWCLK lines for external access. Is it possible to debug the DA14580 using these lines and an ST-Link/V2 debugger in the Keil uVision5 IDE? The Keil IDE has an option in its debug settings to use a ST-Link, but when i set it up like this it fails to attach to the DA14580. I do manage to use the Keil IDE to successfully debug the chip via a PAN USB evaluation module that contains a SEGGER J-Link.
Thanks,
Paul.
