Hi all,
I am currently doing a packet error rate test on CC2541 module. Basically our product streaming out the value of the gyrometer and accelerometer with the connection interval of 20mSec to the host via notification/msg.
With the distance of 5 meter away from the host, sometimes I could get 1 packet error out of few thousands packet received.
Questions:
- Does the BLE have some kind of "acknowledge" mechanism from host, so that the module aware that the host didnt received the packet sent, hence the module will try to resend the packet? or BLE module only able to perform "dumb" sending?
- Is there any workaround to avoid packet error rate, beside improving on the antenna efficiency and matching circuit?
Thank you,
Handi
