I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...

I'm having really terrible RF performance with a PCB I've designed using a nRF51822 QFAC, Johanson 2450BM14E0003 balun, and a PCB IFA (from TI DN0007: www.ti.com/.../swru120b...
I would like to create a large “virtual” read only characteristic that does not fully exist in memory. I understand that large characteristics are transferred in chunks of...
I am trying to enable a critical section in handler. I need to update a sensitive global variable when a button event occurs, and the fact to enable/disable the interrupt...
I have nrf51822 and I use latest SD130. I scan nearby ble devices. In my case they are iPhones. When one device is in rage then I connect to it and start scan again and keep...
Hello to everyone!
So, now I try to enable a DFU for nrf51822 (S110 7.3.0)and have some problems with it.
I can't find a good example project including DFU, all that I...
I've created a simple test to demonstrate pstorage store/load for 64 pages of 1024 bytes each. To allow 64 flash pages I set PSTORAGE_MAX_APPLICATIONS to 64. Each page stores...
I've been following the custom service nAN-36 instructions and have it mostly working on my PCA10028 board, but I have two problems that I just can't figure out. I'm pretty...
I used to be able to see my development kit in nRFgo studio and flashed S110 onto the chip. Now all I see is: "No boards connected". I am still able to flash programs onto...
Hi,
We've been seeing an intermittent connectivity issue in Yosemite in discovering BLE services, namely scanForPeripheralsWithServices does not return anything. The same...
I have based my project on the SDK 6.1 ble_app_hrs. In main.c is included app_gpiote.h which I assume is for the app_button module. However in a separate class I also use...
I'm currently using soft device 110 version 7.1 on a 51822.
I have several characteristics that are more than 20 bytes that as a server I want a client to write to. I actually...
Hi, I'm using the GPIOTE library to detect an interrupt from a sensor, query the sensor and update the gatts value. The problem I've found is that the IRQ priority is hardcoded...

Now i am using NRF51822 of your company. Now we are evaltion thermal character of this component.
So please kindly provide theta JC (junction to case...
Is it acceptable if I stop an app timer for dozens of times when the app timer is actually stopped.
Will the memory leak if I operates in these scenario.Does it affect whether...
I am considering using the nRF51822 for an upcoming project for a client. It is a simple BLE peripheral, so I would use the S110 SoftDevice for the stack. I am looking at...
