Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi,
After setting up constant carrier, how can one determine that it is working. With no modulation the receiver can't determine anything, can it?
thanks
Hi,
SPI use with SDK14.2.0 leads to very high power consumption (around 400 µA) on nRF52832 (QFAA). The same piece of code running with SDK12.3.0 has much lower power consumption...
We developed a device based on nrf51822.
We use SDK11 and module Device Manager to implement bonding.
We have received feedback from the user, that our deivice was bricked...
Hi,all :
I just want to know how to enable the nrf_log (in the ble example).The version of the sdk is 12.3.0 and the cpu is 51822 .Thank you very much .
On the nRF52810 is it posible to change the gain setting for the SAADC on demand? For example the SAADC is reaching its cap and then the gain is increased so it is posible...
I see the max for a BLE connectable advertising packet of 31 bytes. I am not sure if the manufacturer specific data which also can be up to 31 bytes is included in the overall...
Hi,
We have recently moved from using the nRF52840 PDK to a custom PCB. The custom PCB uses nRF52840 Q1AABB, while the PDK has Q1AAAA.
On the custom PCB, the code is getting...
Good evening,
I'm having some difficulties with the thingy52. I used it as the basis of development for the project and up to this point without major problems. However...
IARv8.x.x no longer seems to display the detailed peripheral register settings in debug mode under "View->Registers" as all v7.x.x versions used to do. In trying to determine...
Hi,
I followed this tutorial https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-characteristics-a-beginners-tutorial?CommentId=adb9d7e0-1bf3-49bf...
Hi,
I'm using a nRF52832, SD132, SDK14.2 on a custom board.
I want to use BLE for precision, my use case require me to perform at least 50 reading from the SAADC per second...
Hi,
I'm trying to understand the speed of the BLE communication. What I do in my infinite loop is a SAADC conversion then send the value to BLE (int16_t).
In order to...
Hello,
I have a statically provisioned mesh network (keys and addresses are pre-set in code to make it simple for now) in which each device periodically broadcasts it's...
Hi,
i want to know if there is a solution to apply LE privacy to a timeslot advertisement ?, my problem is :
i have multiple advertisements at the same time (sofdevice...
Hi everyone,
I've gat a problem with advertising. I'm using above mentioned module and Eclipse with GCC compiler, SDK version 14.2.0.
I followed the advertising tutorial...
