Hello, i add a new custom service with one characteristic that allows me to send values over BLE with nRF connect, but i must send some acceptable values (-2, -4, 0, 4, 10 ,20 ,40). My wish is to personalize the write value field of the characteristic to a list of those acceptable values, that if an other user discovers the service, he can only send those values.
iam using sdk 14.2 with dev board nrf52840
regards,
