Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hi, I am trying to code my nRF51822 on my custom board, however right now I'm having my doubt on using some of the example code provided in the SDK.
Essentially, I want...
Hi,
1/ I download the s110 softdevice and ble_app_hrs to the nRF51822 board, and running normally.
2/ I download the s120 softdevice and ble_app_hrs_c to the nRF51822...
Dir sir. I read the white paper "Tuning the nRF24xx matching network" and I have a question.
I would like to know the setting of the spectrum analyzer when I measure the...
I'm looking at the 5.2 SDK and I have noticed a few minor things that may be bugs or might be my mistake but here goes:
In the GCC linker scripts, I was carefully...
Hi,
Recently I want to set up a dynamic network that with the node change this position ,the network will change dynamically.But there is the question,with the node's position...
Hi,
I am working on a keyboard project,I change the HID report as follows
0x05, 0x0C, // Usage Page (Consumer Devices)
0x09, 0x01, // Usage (Consumer Control)
0xA1...
Hi,
How does the advertisement filter policy work?
I tried both BLE_GAP_ADV_FP_FILTER_SCANREQ and BLE_GAP_ADV_FP_FILTER_BOTH, but this doesn't restrict other devices...
Dir Sir. I am checking the current profile of nRF24AP2 in RX mode.
After "open channel" command, I found the peak current at 10ms interval until connection pass.
How does...
I just purchased an mbed developer kit and I am looking for the source code for the device. I want to write an iOS app to interface to this device via BLE. I'd like to have...
Hello,
I am using Nordic's UART service to communicate with my project. I use iOS and also Master Control Panel (with a dongle) on a laptop.
I have two questions:
...
Using ble_app_hrs running on a PCA10004 (nRF6310 motherboard + PCA10004 which uses a PCB antenna), the achieved range at +4dbm (<10m) seems to be short. Master Control Panel...
I think the new MCP might have a bug somewhere. I have not been able to find out the exact sequence on how to provoke it, but I have to restart the application more often...
if I set BLE_GAP_CONN_SEC_MODE_SET_OPEN, I can get data,
but if I set BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM,
Three different even sequences happened, only one sequences...
Hi,
I disconnect the BLE by calling *sd_ble_gap_disconnect*(), and found that it run to *app_error_handler*() after the BLE_GAP_EVT_DISCONNECTED event occured, and I don...
