Hi
I'm attempting to transfer some text strings over ble
I have a nRF51 as master and a AVR & HM-10 module as peripheral.
The peripheral/AVR side I have working fine - When i connect to it via its advertisements, with the nRF Connect app I receive my data string expected.
However I have been unable to get the nRF51 to act as master - i.e Scan, connect to peripheral (using name as filter) then receive/send the serial data.
I can scan and connect to the correct peripheral device but cannot receive any data from it yet.
Using nRF5_SDK_12.3.0, I started with the "ble_central\ble_app_uart_c" example, I took a section from the "ble_app_multilink_central" to get the device name to filter my peripheral to connect to on. - This all works and connects fine.
However after connection I can see that the nRF runs the "db_disc_handler" function (and hence the "ble_nus_c_on_db_dic_evt" function") but than nothing after this.
From the nRF connect app (when connected to my peripheral) I see the following values:
Client - Generic Access UUID 0x1800, Generic Attribute UUID 0x1801 & Unknown Service 0000ff0-0000xxxxxxxxx....
When I 'receive' my data string (in nRF Connect) it comes in a notification from the unknown service (i.e. 0000ff0-00....)
I'm guessing my problem is that my peripheral does not show the nus service, so the nRF does not know what to do with the data.
I 'think' my real question is - How do I receive serial data on a master when the peripheral device does not have the nus id?
Sorry if my question is confusing... think amateur weekend pilot!
Thanks
