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...
I am using nrf51822. Separately BLE and flash are working perfectly alright. But when I comment err_code = ble_advertising_start(BLE_ADV_MODE_FAST); this line flash is working...
Hello,
As per my understanding, SPP was supported by BT Classic and no more supported in BLE. I have a device, which runs SPP. It has to be connected to the BLE client....
Hi, I am now developing a product which uses nrf51422 chip. In this product, I use buttons to turn on and off (since I don't have hard-power cut off circuit, we use system...
Hi
I wonder if the SDK DTM example can be used with a Rhode & Schwarz CMW500 unit. Are the commands compatible with each other, i.e. expected by the CMW500 and DTM example...
Hi,
we're evaluating NRF52 as a platform for a project in the agricultural space and I have some beginner's questions:
Is it feasible to use a timer firing at 100kHz...
Hello,
I created a custom board with the BMD350 module (it has a nRF52832 chip), and I a trying to program it with the BMD300 eval board.
The module on my custom board...
I am using a nRF51422 device with the SDK 11. The task is to transmit battery service data to an application on the phone. I was wondering if there is a tutorial available...
Hi,
I used "ble_image_transfer" sample code and can get the all the stuff I want and now I'm implementing the central device for it,
but somehow I always got the "cccd_configure...
SDK 14.0.0/S132 5.0.0
When a whitelist is in use and during a connection, a call to ble_start_advertising is made to change advertising to a non-connectable type
since...
This keeps happening every time I stop the program for a while and then resume execution.
N.B. I did put a breakpoint trying to catch the problem.

Hi All,
I have more boards on which I have loaded the code ble_app_uart_c (nRF5_SDK_15.2.0_9412b96) which I use as central devices and I have other boards on which I have...
I need to send the following sequence of bits through TWI
start bit | 7 bit address | write | slave ACK | stop bit
I looked through the twi_hw_master.c and it seems...
When building a project that compiles the hal_nfc_t2t.c, it errors for nRF52840, but works for nRF52832.
For the nRF52840, I get these errors:
Looking for some of the...
Hello, I want to transfer a large file (approx. 1.5MB) over BLE using nRF52 Module in a way where BLE Host and BLE Controller will be on the nRF52 SoC and the application...
