Hi,
We use nrf51 SDK v9. I found there are two SER_MAX_CONNECTIONS defined both in app_ble_gap_sec_keys.h and ser_config.h. Their values are different. One is referred...
Hello,
I have a problem when I try to use cheaper Android phones to communicate with our 52832 chip.
I can discover the peripheral and then connect, but when I device...
