i used nrf51822 and cant find 128 bit uuid but other chip is good

[lvyapeng]

Hi,

i use nrf51822 and  sdk  11.0 . I am using the ble_app_hrs_c example .This product consists of two devices，One master and one slave.

The master chip is  nrf51822，but，I don't know what the slave chip.I need to communicate with the serial port service of the slave.

The UUID of the slave serial port service is not the standard 128 bit UUID。but，I can't find the UUID of the serial service。

I use another Bluetooth chip as the host to connect to the slave and find the serial port service. It is successful and all communication is normal. However, using nrf51822 is not good。

It tells me that I can't find the service，I need to find the UUID of the service is 0x9ac4。but，is not 。

Hi,

I assume you are getting a ble UUID type unknown when trying to dicsover the service? To find this 128bit uuid you need to perform a sd_ble_gattc_attr_info_discover. then add the UUID to your vendor specific UUID's. Or you need to add the UUID as vendor specific UUID before the service discovery procedure.
