DA14580主从设备，我想1秒内发送只是500字节到主设备，使用Nofity还是Read好呢？ 好像都受MTU的限制，MTU要如何更改呢，atts_mtu_exc_resp (uint8_t conidx, struct l2cc_att_mtu_req* req);这个函数来协商吗？
我用定时器来Nofity发送数据时，我在gattc层使用gattc_set_mtu() 和gattc_get_mtu()，也在usr_config更改了max mtu，但是定时器死掉了。
Two DA14580 devices are master slave relationships,I want to change MTU to 53 or 153, should I use gattm_set_max_mtu() to change before the connection and negotiate after the connection is successfully?
I used them to try, but after sending the data, the device suddenly got stuck:
gattm_set_max_mtu(53);
tu = gattm_get_max_mtu();
gattc_set_mtu(connection_idx,tu);
get_mtu = gattc_get_mtu(connection_idx);
app_prf_enable(param->conhdl);
你好,我使用的是DA14580, SDK5.0.4 /项目/ target_apps / ble_examples/ble_app_all_in_one.
我使用系统定时函数app_easy_timer（），遇到了一个问题。
我调用这个函数之后，只要加入app_easy_timer_cancel（）函数,那么下面的函数只会循环一次。
Hello,
The Murata module DA14580 is used. Often you will find lost data. Excuse me. Under what circumstances, the DA14580 may have lost data.
How to set up a specific data channel for data transmission. For example: data channel 35. Is it possible to set this up?
Hi All,
What is the long term (15-20 years) stability and ageing data for the RC OSC, not being crystal based? how would it impact counter delays timing?
Thanks,
Hello,
We are using PAN170 BLE module based on DA14580.
We would like to do South Korea KC Certification for our product.
To do that we need to be able to control some aspects of BLE radio.
Is there any software (binary) available to have more control over BLE radio?
We would need:
目前我们使用的是boost模式，使用一块工作正常的DA14580 电路板，
我们测试：
使用直流电源，设置电压为1.1v，连接DA14580电路板, 此时DA14580正常工作。
但当我们如下操作时：使用直流电源，设置电压为0.7v，连接DA14580电路板， 我们将直流电源电压慢慢抬高（模拟充电电池的电压缓慢升高），当电压等于0.75v时，就有2mA的电流产生，紧接着继续抬高电压，电流随之增大，当电压到达1.15v时，电流增加到32 mA左右，超过1.15v时，DA14580 恢复正常工作。
1.请问这是什么原因，有什么办法避免 电压缓慢上升时，DA14580 大电流耗电的问题？
Hello All,
I have attempted to import data points (custom signal) in milliseconds and millivolts for X and Y respectively, below is a sampling of the data points, however i get the below message when executing the test option, has anyone tested the import, I followed the info format under info box, but without success. Any help is much appreciated.
Thanks,
