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...

Hi there:
I found a strange phonomenon about consumption betweeen advtisement and gpio17 of 51822.
When I start ble adv while setting gpio17 to input disconnected mode with...
Hi, possibly a bit of a stupid question but here we go:
I'm developing a prototype system, which includes my own design of sensor modules that transmit their data via nrf24l01...
Hi, Nordic
I know when I program one BLE app, softdevice should be needed.
If I program esb/gazell app, softdevice is not needed.
I want to know, when I program one...
Hi, Nordic
I want to add BLE DFU service in my own app, so that the nRF52 can operate BLE DFU.
I only modify 2 places:
static void services_init(void) --> init ble_dfu_init_t...
Hi,Nordic
I am working for BLE_DFU, on SDK 12.1 and SoftDevice s132.
I checked, I should add below code in ble_dfu.c
char_md.char_props.write = 1;
Then I added...
Hi, Nordic
I check SDK13.0 bootloader_secure sample, it do not work
