I'm testing ble_app_peripheral. And I add some debug info to uart2 use arch_printf as flows.
+++add a printf count++
static int count=0;
void custs1_init(void)
{
// Reset environment
memset(&custs1_env, 0, sizeof(custs1_env));
// Create CUSTS1 task
ke_task_create(TASK_CUSTS1, &TASK_DESC_CUSTS1);
// Set task in disabled state
ke_state_set(TASK_CUSTS1, CUSTS1_DISABLED);
Where has the DA14580 system clock block diagram?
Hello,
我有一个问题关于当前消费with NFM. I did measurements with and without NFM and i did't see a signifficant reduction of the power. The output power is -20dBm so normally you have a factor of 100.
I also find a post about the near field mode

Hello!
VDD needs to be larger than VDD2.
the I2C circuitry is referenced to VDD. this does not sound logical in a dual supply system, where the largest voltage could be a battery eg. li-cell and the lower voltage a regulated supply rail for logic, MCU etc. what purpose was intended to refer the I2C to the higher voltage rail ?
hi, we have exact hardware(PCB) as that of proximity reference design and I could burn the proximity smart tag firmware and able to communicate with it. My setup is fine. I use SmartTags android app to test it. I am trying to modify the firmware and connect with the app. Initially it works but after some time it goes for sleep and it never shows up in the android app. Please let us know the solution for this. Even the example firmware without modifying the code also am seeing this behavior. Is there anyway to reconfigure or avoid the sleep mode..etc. Help needed, thank you.
Hi,
I am working on a project wherein the dialog DA 14580 chip communicates with a temperature and humidity sensor via I2C. The testing is performed on the PRO board.
Pin P1_3 is configured as SCL and P0_4 is configured as SDA. I am not able to get the communication proper using these gpio assignments. Now, when I change the SCL configuration to pin P0_7 and SDA is still P0_4, the communication works well and the temperature and humidity readings are proper. Please suggest the reason for the same.
Thanks

Hello,
I have one question regarding the file programmer_es5.bin, mentioned in the AN-B-020.
I'm using a PAN1740 module and I need to burn custom firmware in its OTP. I have sucessfully established UART communication between SmartSnippets and the module, since I can load the firmware through the booter funcionality.
Hi,
i have a question about a power consumption when advertising BLE packets,
here are the events or stages of the advertising:
Pre-processing
Standby + HFXO ramp
Standby
Radio startup + CPU
Radio TX
Radio switch
Radio RX
Any one have an idea about the values of the length(us) and the Avg.current consumtion(uA) of each event?
For example: configuration of 1000ms ADV_INT @0dBm
Thanks,
Regards,
Dear Dialog_Support Team,
As I am developing battery operated device, device is configured with extended sleep mode for longer battery life. And device is also configured with advertising interval of 500ms to save battery. Now using USER_ADVERTISE_DATA, I am broadcasting data. Now as i press push button on custom board, few bytes are changing in advertising data string for 5 seconds. So what I want is for that particular 5 seconds can I make advertising interval small(for ex. 100ms) and rest of time it should remain 500ms.
