I occasionally get an NRF_ERROR_NO_MEM error when trying to add a custom characteristic. I'm only using 3860 bytes of ZI data, stack = 2048, heap = 2048 so it seems like I...
Hi
I am working on the ble_central_and_peripheral example in nRF51_SDK_8.1.0_b6ed55f .In this example it is possible for us to connect to 3 peripherals only.But we would...
Hi, are there any examples in C for how to directly access the registers on the chip? I realize this is a super basic question, but all the register access in the examples...
Hi,guys
I set BLE parameters like this:
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(500, UNIT_1_25_MS)
#define MAX_CONN_INTERVAL MSEC_TO_UNITS(1000, UNIT_1_25_MS)
#define...
Hi,
I'm using sd_ble_gap_connect to connect to a set of known address and whitelisted devices. My central periodically (once an hour) needs to check on a known set of devices...
